coreboot handles this remapping scenarios for PCH and CPU PCIe root
ports and not for TBT root ports.

Frequency and updates Nominal Performance. It uses below calculation to
update the Nominal Frequency and Nominal Performance:
Nominal Frequency = Max non-turbo ratio * cpu_bus_frequency
Nominal Performance = Max non-turn ratio * cpu scaling factor
CPU scaling factor varies in the hybrid core environment. So, the

scaling factor.

contain a PIRQ mapping for UART4. The reference code has a mapping for
this and it uses PIRQ mapping index 0x77 for UART4 and not for I2C5.
Since the I2C5 controller isn't owned by the x86 side and I didn't see
any mapping of the I2C5 controller into the x86 MMIO space, this seems
very plausible. Also add the corresponding fields to the ACPI code.

Since other related platforms (WHL, CFL) share the SoC code but use

This patch extends `struct pad_config` to add new variable for gpio
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)

TEST=Able to build and boot brya variant with this code change.
