OMAP4: DSS2: Create a DSS features structure for OMAP4430 ES1.0
Create a separate DSS features structure for OMAP4430 ES1.0. This structure is used to expose features only present in such silicon version. Specifically, this is required to handle how the HDMI IP calculates the CTS parameter for audio clock regeneration packets. OMAP4430 ES1.0 is the only one that supports computation of the CTS parameter by the HDMI IP (hardware mode). The rest of the revisions require the HDMI driver to perform the computation.
