[PATCH v6 3/3] OMAP: DSS2: OMAPFB: Allow usage of def_vrfb only for omap2,3

[Guruswamy Senthilvadivu <svadivu@ti.com>]

From: Senthilvadivu Guruswamy <svadivu@ti.com>

VRFB is supported only on OMAP2 and OMAP3 platforms. If VRFB rotation is 
not supported by the hardware and the user requests VRFB rotation, 
print a warning and ignore the request from the user.
