soc/amd/common: Don't program GPIOs if the table isn't set

Currently, there's no check for the table being programmed.  This skips
programming a table if the table size is zero, or the pointer to the
table has been set to NULL.

BUG=None
TEST=Set table pointer to NULL, table doesn't run.
BRANCH=Zork
