ARM: OMAP: mcbsp: Make tranceiver configuration control register access generic

Browse Source 
McBSP transmit and receive configuration control registers must be set up
for OMAP2430 and later. Replace is_omap tests in generic code with a new
feature flag has_ccr in platform data so that there is no need to change
code for any upcoming OMAP version.
