ARM: OMAP: mcbsp: Implement generic register access
Register access can be made more generic by calculating register address offsets runtime from common register definitions and by using reg_size and reg_step variables that are passed via platform data. Common register definitions are possible since McBSP registers are ordered similarly between OMAP versions. Remove also references to OMAP2+ specific config_type variable from generic McBSP code since other variables and feature flags are better to carry needed information from platform code.
