We get these warnings when build kernel W=1:

drivers/gpu/drm/panfrost/panfrost_mmu.c:435:5: warning: no previous prototype
for ‘panfrost_mmu_map_fault_addr’ [-Wmissing-prototypes]
For file panfrost_mmu.c, make functions static to fix this.
For file panfrost_perfcnt.c, include head file can fix this.
