ARM: dts: Add common mcpdm dts file for omap4
The mcpdm module found on omap4 and 5 needs pdmclk clock from the pmic that may or may not be wired. Without this clock we cannot read the registers for mcpdm at all. For the external mcpdm clock to work, it needs to be muxed at the module level for ti-sysc driver probe to mux it early enough for probe. Let's set up a common file for it to make things a bit easier to make l4 abe interconnect to probe with ti-sysc driver. Note that this is not needed for omap5 as we can just update mcpdm muxing in omap5-board-common.dtsi in later patches.
