omap2: McBSP: Remove mux code for OMAP2420 McBSP2 and do cleanups
This 'legacy' OMAP2420 McBSP2 muxing code is currently broken after recent conversion to new mux code. The omap_mcbsp_request calling this code is usually called after booting whereas the omap_mux_init_signal is __init marked so null pointer dereference would occur. Fix this by removing the muxing code and let the bootloader or board file to do it if necessary. Remove also omap2_mcbsp_ops as there is no use for it.
