Introduce omap_vout_vrfb.c and omap_vout_vrfb.h, for all VRFB related API's,
making OMAP_VOUT driver independent from VRFB. This is required for OMAP4 DSS,
since OMAP4 doesn't have VRFB block.
Added new enum vout_rotation_type and rotation_type member to omapvideo_info,
this is initialized based on the arch type in omap_vout_probe. The rotation_type
var is now used to choose between vrfb and non-vrfb calls.
