The mainboards mc_apl{2,4,5,6} use VBOOT for verification and can be in
a recovery state for different reasons. In this case we still want the
MRC cache to be around to avoid the DRAM retraining on every boot.
This patch enables the Kconfig switch HAS_RECOVERY_MRC_CACHE which makes
the already available MRC recovery region in FMAP useable.
Test=Boot mc_apl2 in recovery mode and make sure the recovery MRC
cache is used.

The only option to make HECI1 function disable on Elkhart Lake SoC

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.
Mainboards that choose to make HECI1 enable during boot don't override
`heci1 disable` config.

buffer in memory which is 256 bytes long (as FSP requests minimum 256
bytes for the SPD data) and where the upper 128 bytes are taken from
HW-Info holding the needed timing parameters for LPDDR4.
If there is a case where HW-Info is not accessible or where the
contained SPD data is not valid (by checking the CRC in HW-Info SPD)
fall back to fixed SPD data set in CBFS.

Some legacy devices need to have the master bit set in the PCI config
due to old drivers not setting it correctly. Set the master bit if the
feature is enabled via Kconfig switch PCI_ALLOW_BUS_MASTER_ANY_DEVICE.

master bit to be set.
