ASoC: omap-mcbsp: Single function CLKR/FSR source mux configuration
Use single function for the CLKR/FSR mux configuration.
OMAP2/3 has 6 pin configuration on McBSP1 instance, while on OMAP4
McBSP4 instance have the 6 pin configuration so the omap2_mcbsp1_mux_* is
not correct name for all support OMAP versions
