drm: Miscellaneous fixes for v3.19-rc1

This is a small collection of fixes that I've been carrying around for a
while now. Many of these have been posted and reviewed or acked. The few
that haven't I deemed too trivial to bother.

* tag 'drm/fixes/for-3.19-rc1' of git://people.freedesktop.org/~tagr/linux:
  video/hdmi: Relicense header under MIT license
  drm/gma500: mdfld: Reuse video/mipi_display.h
  drm: Make drm_mode_create_tv_properties() signature consistent
  drm: Implement drm_get_pci_dev() dummy for !PCI
  drm/prime: Use unsigned type for number of pages
  drm/gem: Fix typo in kerneldoc
  drm: Use const data when creating blob properties
  drm: Use size_t for blob property sizes
