drm/msm: adreno: fix deferencing ifpc_reglist when not declared
On plaforms with an a7xx GPU not supporting IFPC, the ifpc_reglist
if still deferenced in a7xx_patch_pwrup_reglist() which causes
a kernel crash:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008

Check the validity of ifpc_reglist before deferencing the table
to setup the register values.
