soc/amd/common: Revert PI blob search hack

Remove the check for CONFIG_VBOOT when finding the binaryPI blob and
rely on the cbfs search 100% of the time.  The change was initially
put in to avoid a hang when vboot presearched memory for the blob.
The implementation now supports early cbmem init and cbmem_top() is
careful to return 0 if DRAM has not yet been set up.  As a result the
hang no longer occurs and the hack may be removed safely.
