omap: McBSP: Use macros for all register read/write operations
There are several places where readw()/writew() functions are used instead of
OMAP_MCBSP_READ()/WRITE() macros for manipulating McBSP registers. Replace
them with macros to ensure consistent behaviour after caching is introduced.
Tested on OMAP1510 based Amstrad Delta.
Compile-tested with omap_3430sdp_defconfig.
