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.

v5: Fixed the caller of this function in omapdrm to comply with supported
bitmask definition.

How can it be v5 w/o any v2,v3,v4?

In any case I think this is still broken. I'll reply with a new patch...
