soc/intel/common: use prog_locate() for finding fsp.bin

The current method was only taking the cbfs path. Because
of this fsp.bin was never being utilized from the RW slots.
Using prog_locate() now provides both the cbfs and vboot
locate methods for free.

BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built and booted glados.
