This brings the ACPI code more in line with both what the new code for
the AMD SoCs will do and also what the current Intel code does. This was
mainly done to have a reduced delta to the new AMD domain resource
handling functions to debug it, but it might still be useful to upstream
this change.

The enum macro is named `sagv_wp_bitmap` and it has three values:
The goal is to choose the optimal SaGv work point for the target
platform after considering the two inputs as power consumption and performance. The first group is for workloads that require high performance, even if it means consuming more power. The second group
is for workloads that can tolerate lower performance, in order to save
power.
SAGV_POINTS_0_1: The highest power consumption, but also the highest
performance.
SAGV_POINTS_0_1_2: A lower power consumption than work point
SAGV_POINTS_0_1, but also a lower performance.
SAGV_POINTS_0_1_2_3: The lowest power consumption, but also the lowest
performance.

Currently the SPI ROM is mapped completely when the boot device is
initialized. That mapping remains active throughout the execution time
of PSP verstage. Every 1 MiB of mapped SPI ROM region consumes 1 TLB
Slot in PSP for use during memory mapped or DMA access. With 16 MiB of
mapped SPI ROM + FCH devices + 4 reserved TLB slots, 31 out of 32 total
TLB slots is consumed. This leaves almost no scope for future expansion.
With upcoming programs possibly using 32 MiB SPI ROM, PSP will run out
of TLB slots to support 32 MiB.
Hence instead of mapping the entire SPI ROM upfront, get the SPI ROM SMN
address during the boot device initialization. Update the boot device
region operations to map and unmap the SPI flash with the desired offset
and size using the SVC call. Then anytime a memory mapped SPI ROM access
is performed: map the required area, read the data and immediately unmap
the area. There is no update required when using CCP DMA, since the
concerned SVC call performs mapping and unmapping of the required SPI
flash area implicitly.
With these changes, maximum of 8 slots(size of RO section) might get
used at any point in time during the PSP verstage execution.

In GEN_PMCON1 (Offset 1020h), Bit 0 is the "After G3 Enable" (ag3e)
(source Intel document #569262). Only use 8 bits, in the same way as
most other Intel SOCs do, for pmc_soc_set_afterg3_en.

The return value of cse_get_bp_info() is an enum integer, where zero
means success and non-zero means failure. The function
store_cse_rw_fw_version() calls the function cse_get_bp_info() and
validates the return value as a boolean causing prematurely returns of
the parent API even if cse_get_bp_info() is successful.
This patch corrects this logical error by returning only if
cse_get_bp_info() fails.
TEST=Build and boot google/nivviks and verify that the ISH version info
command is only being sent during cold boot.

If the ME is disabled with the `me_state` CMOS setting, boot
times are approximately 5 seconds longer:
942:before sending EOP to ME 1,240,773 (5,599)
943:after sending EOP to ME 6,263,951 (5,023,177)
Total Time: 6,167,443
This is because the current code only checks if the ME is
disabled for CSE LITE SKUs. With this patch, boot times are
approximately 5 seconds quicker:
Total Time: 1,143,932
Tested on `starbook/adl` and `starbook/tgl`.
