Paul: What's your opinnion, would it be possible or would it be wise to
handle these McBSP clock route setups with the clock framework instead?
Functions omap_mcbsp_dai_set_clks_src and omap_mcbsp_dai_set_rcvr_src
are basically just setting up the input clock for McBSP SRG or McBSP1

OMAP1 can include control.h as well :-)
Access is anyway protected with the cpu_class_is_omap1().
