…s static

This symbol is not used outside of panfrost_drv.c, so marks it static.

Fix the following sparse warning:

drivers/gpu/drm/panfrost/panfrost_drv.c:641:12: warning: symbol
'mediatek_mt8183_supplies' was not declared. Should it be static?

drivers/gpu/drm/panfrost/panfrost_drv.c:642:12: warning: symbol
'mediatek_mt8183_pm_domains' was not declared. Should it be static?
