OMAP4: DSS2: Create a DSS features structure for OMAP4430 ES1.0

Browse source 
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.
