Subject: [PATCH 1/2] drm/bridge: adv7511: fix Wvoid-pointer-to-enum-cast warning

'type' is an enum, thus cast of pointer on 64-bit compile test with W=1
causes:

  adv7511_drv.c:1214:19: error: cast to smaller integer type 'enum adv7511_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
