This patch adds routines to keep CSE and other HECI devices into the
lower power device state (AKA D0I3).
- cse_set_to_d0i3 => Set CSE device state to D0I3
- heci_set_to_d0i3 => Function sets D0I3 for all HECI devices
Additionally, creates a config `MAX_HECI_DEVICES` to pass the HECI
device count info from SoC layer to common CSE block.
As per PCH EDS, the HECI device count for various SoCs are:
ADL/CNL/EHL/ICL/JSL/TGL => 6 (CSE, IDE-R, KT, CSE2, CSE3 and CSE4)
APL => 1 (CSE)
SKL/Xeon_SP => 5 (CSE, IDE-R, KT, CSE2 and CSE3)

lock action.
Additionally, it creates new GPIO PAD configuration macros that perform
GPIO pad configuration and pad lock configuration as well.
List of new macros are:
1. PAD_CFG_NF_LOCK
2. PAD_CFG_GPO_LOCK
3. PAD_CFG_GPI_LOCK
4. PAD_CFG_GPI_TRIG_OWN_LOCK
5. PAD_CFG_GPI_GPIO_DRIVER_LOCK
6. PAD_CFG_GPI_INT_LOCK
7. PAD_CFG_GPI_APIC_LOCK
8. PAD_CFG_GPI_IRQ_WAKE_LOCK
Mainboard users can use the above macros to lock the PAD after
configuration.
So far on IA chipset, the default GPIO pad lock configuration reset
type is POWERGOOD hence, it's recommended as per GPIO BWG (doc: 630603)
to configure the GPP PAD reset type the same as lock configuration
reset type to avoid GPP reset value misconfiguration issue.

This patch performs GPIO PAD lock configuration in non-smm mode.
Typically, coreboot enables SMI at latest boot phase post FSP-S,
hence, FSP-S might get chance to perform GPP lock configuration.
With this code changes, coreboot is able to perform GPIO PAD
lock configuration early in the boot flow, prior to calling FSP-S.
Also, this patch ensures to have two possible options as per GPIO
BWG to lock the GPIO PAD configuration.
1. Using SBI message with opcode 0x13
2. Using Private Configuration Register (PCR)

The TCO timer is the default watchdog of an x86 host and can reset the
system once it has expired for the second time. There are applications
where this reset is not acceptable while the TCO is used. In these
applications the TCO expire event generates an interrupt and software
takes care. There is a bit in the TCO1_CNT register on Elkhart Lake to
prevent this reset on expiration (called NO_REBOOT, see doc #636722 ).
This bit can either be strapped on hardware or set in this register to
avoid the reset on expiration. While the hardware strap cannot be
overridden in software, the pure software solution is more flexible.
Unfortunately, the location for this bit differs among the different
platforms. This is why it has to be handled on soc level rather than on
TCO common code level.
This commit adds a Kconfig option where NO_REBOOT can be enabled. This
makes it easy to reach this feature over to the mainboard where it can
be selected if needed.

Since Tiger Lake platform, the HECI1 device can be disabled on
Alder Lake platform using two different mechanism:
A. Using PMC IPC command 0xA9.
B. Sending SBI message under SMM.
In current scope of Alder Lake the default implementation is using
(B) sending sbi message under SMM. A follow up patch to add the
possible options and let platform to choose the applicable one.
List of changes:
1. Drop `HeciEnabled` from dt and dt chip configuration.
2. Replace all logic that disables HECI1 based on the `HeciEnabled`
chip config with `DISABLE_HECI1_AT_PRE_BOOT` config.
3. Default enable HECI1 device in `chipset.cb` to ensure the HECI1
device can undergo the PCI enumeration and later based on the
mainboard policy the HECI1 device can be disabled.
Mainboards that choose to make HECI1 enable during boot don't override
`DISABLE_HECI1_AT_PRE_BOOT` config.

The Intel® Programmable Services Engine (Intel® PSE) is a
dedicated offload engine for IoT functions powered by an ARM
Cortex-M7 microcontroller. It provides independent, low-DMIPS
computing and low-speed I/Os for IoT applications, plus
dedicated services for real-time computing and time-sensitive
synchronization.
The PSE hosts new functions, including remote out-of-band
device management, network proxy, embedded controller lite
and sensor hub.
This CL enables the user to provide the base address of the
PSE FW blob which will then be loaded by the FSP-S onto the
ARM controller. PSE FW will do the initialization work of
PSE controller and its peripherals. The loading of PSE FW
should have negligible impact on boot time unless PSE
controller could not locate the PSE FW and FSP will attempt to
redo PSE FW loading and wait for PSE handshake until it times
out. Once PSE controller locate the PSE FW, it will do
initialization concurrently by itself with coreboot booting.
It also adds PSE related FSP-S UPD settings which enable the
setup of peripheral ownership (assigned to the PSE or x86
subsystem) and interrupts. These assignments need to take
place at a given point in the boot process and cannot be
changed later.
To verify if PSE FW is loaded properly, the user could enable
PchPseShellEnabled flag and the log will be printed at PSE UART
2.
For further info please refer to doc #611825 (for HW overview)
and #614110 (for PSE EDS).

When calling get_pcie_rp_pmc_idx(), the following code checked the
return value to see if it was negative or `> CONFIG_MAX_ROOT_PORTS`.
However, the expected return value for CPU PCIe RPs is above
MAX_ROOT_PORTS. Since the static, local function is intended to return
-1 or a valid value, drop the check for `> CONFIG_MAX_ROOT_PORTS`.
