soc/amd/common/pm/pmlib: use PM register mapping in ACPIMMIO region
In all SoC pm_set_power_failure_state gets called either after a call to
enable_acpimmio_decode_pm04() or the ACPIMMIO mapping is already enabled
after reset on the SoC. This allows to use pm_read8 and pm_write8 that
use the ACPIMMIO mapping of the PM registers instead of pm_io_read8 and
pm_io_write8 which won't work on Phoenix and Glinda due to the IO ports
used on older generations to access to the PM registers not being
implemented any more.
