Hello, DRM maintainers!

Laurent Pinchart kindly agreed to allow me to pick up his work on
the generic colorkey DRM plane property [0]. I've reworked the original
patch a tad, hopefully making it flexible enough to cover various HW
capabilities.

Changes I've made:

	- Some code clean up and reshuffle.

	- Took into account some the Ville's Syrjälä review comments to [0].

	- The number of common DRM colorkey properties grows from 4 to 9.
	  New properties:
		- colorkey.mask
		- colorkey.format
		- colorkey.inverted-match
		- colorkey.replacement-mask
		- colorkey.replacement-format

	  Renamed properties:
		- colorkey.value -> colorkey.replacement-value

	- colorkey.mode userspace-property ENUM's got a bit more explicit
	  names, like "src" -> "src-match-src-replace".

	- No driver-specific modes / properties allowed, all unsupported
	  features are simply rejected by the drivers.

This patchset includes initial colorkey property implementation for the
older NVIDIA Tegra's.

Please review, thanks.
