drm: Add support_bits parameter to drm_property_create_bitmask()
Make drm_property_create_bitmask() a bit more generic by allowing the
caller to specify which bits are in fact supported. This allows multiple
callers to use the same enum list, but still create different versions
of the same property with different list of supported bits.
v2: Populate values[] array as non-sparse
Make supported_bits 64bit
Fix up omapdrm call site (Rob)
