[M] Change in coreboot[main]: UPSTREAM: soc/mediatek/mt8188: devapc: set devapc permission for MFG

[Fei Yan (Code Review)]

Fei Yan has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/82076?usp=email )

Change subject: UPSTREAM: soc/mediatek/mt8188: devapc: set devapc permission for MFG
......................................................................

UPSTREAM: soc/mediatek/mt8188: devapc: set devapc permission for MFG

Set MFG to domain 6.
Set MFG remap in infra and sub infra, so that MFG can switch to protect mode by MFG register.
Set MFG slave MFG_S_S-2 and MFG_S_S-5 permission from NO_PROTECTION to SEC_RW_ONLY for domain 0
So that only AP in secure mode can access MFG_S_S-2 and MFG_S_S-5

BUG=b:313855815
TEST=emerge-geralt coreboot
