soc/amd/picasso: Allow use of pre-built PSP verstage 

To use a signed PSP verstage, we're going to need to build it first,
then sign and store the binary.  This patch allows the stored (signed)
verstage binary to be used.

BUG=b:166108929
TEST=Build with existing verstage binary instead of re-building it.
BRANCH=Zork
