There are currently two issues related to the WLAN power sequencing on
nereid:
- If the EN pin GPP_B11 is not high during cold boot, the SoC gets stuck
in S3.
- During warm reboot, if we only assert RST without pulling the power
low, then the kernel crashes.
As a workaround while we investigate these issues, we pull the EN high
in S5, then actively drive it low in bootblock and high in romstage to
make sure it goes low during warm reboot.
BUG=b:227694137, b:225261075
TEST=Cold boot succeeds, and there's no kernel crash during warm reboot.

Some bytes in the descriptor need to be set differently for Type-C and
HDMI. To allow using a single firmware variant for both cases, update
the descriptor at runtime based on fw_config. This is a temporary
workaround while we find a better solution.
The byte values were determined by changing the following CSE strap and
comparing the generated descriptors:
Type-C: TypeCPort2Config = "No Thunderbolt"
HDMI: TypeCPort2Config = "DP Fixed Connection"
The default value before updating the descriptor is Type-C, but this was
chosen arbitrarily.
BUG=b:226848617
TEST=Type-C and HDMI both work on nereid with fw_config set correctly.

Chause doesn't get to x86 bootblock without the SPL table binary in the
PSP directory table, so I assume that Majolica won't get to x86
bootblock either, since the Cezanne SoC default is not to include any
SPL table binary. This was caused by a combination of
commit 6c5ec8e31c (amdfwtool: Add options
to support mainboard specific SPL table) that caused a regression in
amdfwtool and commit c5b912f788
(soc/amd/cezanne: Allow to specify SPL table path in Kconfig) that
removed the default for the Cezanne SoC. Fix this by adding the default
SPL table file back to the fw.cfg file which will get ignored by
amdfwtool when a mainboard selects SPL_TABLE_FILE and specifies another
SPL table binary.

to update the temporary variable range MTRRs and showed ~44ms of boot
time savings as below:

90:starting to load payload 1,084,052 (14)
15:starting LZMA decompress (ignore for x86) 1,084,121 (68)
16:finished LZMA decompress (ignore for x86) 1,140,742 (56,620)
After:
90:starting to load payload 1,090,433 (14)
15:starting LZMA decompress (ignore for x86) 1,090,650 (217)
16:finished LZMA decompress (ignore for x86) 1,102,896 (12,245)

This patch delays removing `temporary` MTRR snapshots to avoid conflicts
with other operations attached with same `BS_PAYLOAD_BOOT/BS_ON_EXIT`
boot state.

TEST=Having variable MTRR snapshot using display_mtrrs() is able to
list only the permanent MTRRs and all temporary MTRRs are removed
prior to boot to payload.

This patch replaces the implementation that is used to get the number of
variable MTRRs with `get_var_mtrr_count()` function.

This patch migrates a few useful MTRR functions as below from
`earlymtrr.c` file to newly created common stage file `mtrrlib.c`.
1. get_free_var_mtrr
2. set_var_mtrr
3. clear_all_var_mtrr
These functions can be used to perform the MTRR programming from IA
common code SPI driver as `fast_spi.c` without requiring two separate
implementations for early boot stage (till romstage) and for ramstage
onwards.
