[Kyösti Mälkki (Code Review)]

Hello build bot (Jenkins),

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

soc/amd/common: Inline ACPI MMIO accessors

The overhead of pushing variables to stack exceeded the number
of instructions the actual MMIO operation took and the build of
google/aleena with inlined accessors turned out to be just
slightly (<2 KiB) smaller for the entire romstage or ramstage.
Simple read-modify-write MMIO cycles should optimise better now.

IO cycles with index/data register are borderline, at
first sight assembly looked better by not inlining them.
