cpu/amd/pi: Change wrapper to use config option
Add a check for vboot when locating the binaryPI image.
There is currently an ordering problem using cbmem to locate the
image when vboot is present. Vboot inserts its locator into the
search process so that memory can be checked before flash is queried.
For the earliest calls using the wrapper, DRAM has not been set up
and cbmem not initialized in romstage. This change prevents an
endless loop when vboot searches cbmem.
This change has another side effect. When vboot is in effect, the
change forces the RO binaryPI to be used even when on either of the
RW paths. There is currently no ability to relocate the XIP image
for use in a RW region.
