Revert "soc/amd/common/block/acpimmio: Update acpimmio for psp_verstage"

This reverts commit 4883252912.

Almost everything in <amdblocks/acpimmio_map.h> is invalid for PSP as
it does not have the same view of memory space.

The prototypes xx_set/get_bar() are only valid for PSP as x86 cores
will use the constant mapping defined in <amdblocks/acpimmio_map.h>

The selected MMIO base address model depends of the architecture the
stage is built for and, to current knowledge, nothing else. So
the guards should have been with ENV_X86 vs ENV_ARM and not about
CONFIG(VERSTAGE_BEFORE_BOOTBLOCK).

For the ENV_ARM stage builds, <arch/io.h> file referenced in the
previously added mmio_util_psp.c file has not been added to the tree.
So there was some out-of-order submitting, which did not get caught
as the build-testing of mixed-arch stages has not been incorporated
into the tree yet.

The previously added file mmio_util_psp.c is also 90% redundant with
mmio_util.c.
