Add new registers specific to UV color component that are introduced in OMAP4. Add simple helper functions to configure the newly added registers. These new registers are mainly: - UV base address registers used specifically for NV12 color-format - FIR registers used for UV-color-component scaling on OMAP4 - Accumulator registers used for UV-color-component scaling Add these new registers to save/restore and DUMPREG functions. Also add two new features for OMAP4: - FEAT_HANDLE_UV_SEPARATE - this is used on OMAP4 as UV color-component requires separate handling. - FEAT_ATTR2 - this is used on OMAP4 to configure new ATTRIBUTES2 register.
