[coreboot-gerrit] Change in coreboot[master]: soc/amd/common/block/acpimmio: fix ACPIMMIO decode enable function

[Michał Żygowski (Code Review)]

Hello Kyösti Mälkki, Marshall Dawson, build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/37178

to look at the new patch set (#10).

soc/amd/common/block/acpimmio: fix ACPIMMIO decode enable function

According to BKDGs for families 15h 60-6fh or newer and families 16h the
ACPI MMIO decode enable bit is the second LSB, not the first LSB.

Additionally create another enable function for older families where
the register and bit is different.

It does not seem to impact any current board, but may be crucial for
incoming C bootblock implementations when this bit will need to be set
very early. Most likely this bit is set by AGESA right now.
