soc/intel/cmn/gfx: Join MBUS while FSP-S performs GFX init

This patch calls into the function to join the MBUS if the GFX PEIM
module inside the FSP binary is taking care of graphics initialization
based on the RUN_FSP_GOP config option. The FW skips joining the MBUS
in case of a non-FSP solution and/or SOC_INTEL_GFX_MBUS_JOIN config is
not enabled.

BUG=b:284799726
TEST=MBUS joining is only applicable for google/rex while using GFX
PEIM.
