[PATCH] ARM: davinci: da850: add clocks for mcbsp0 and 1

Add clock definitions "davinci-mcbsp.0" and "davinci-mcbsp.1" in order
to make McBSP driver work on the DA850 platform.
The McBSP 0 and 1 interfaces were not defined for the DA850 platform.
Neither were the related clocks. In order to make the use of McBSP via
devicetree the clocks need to be defined.
