Merge branch 'drm/next/platform' of git://linuxtv.org/pinchartl/media into drm-misc-next

Browse Source 
Merge Laurent's drm_platform removal code. Only conflict is with the
drm_pci.h extraction, which allows me to fix up the misplayed
drm_platform_init fumble that 0day and Stephen Rothwell reported.
