soc/amd/common: move block/pi out of the block folder
Since the binaryPI glue code is specific to a binary interface, but not
for a hardware block, move it out of the common blocks directory. This
also brings the binaryPI support in line with the FSP support which is
used on the newer generations. This also drops the
SOC_AMD_COMMON_BLOCK_PI Kconfig option and makes use of the already
existing SOC_AMD_PI Kconfig option instead.
