bus: ti-sysc: Add mcasp optional clocks flag
We have OPT_CLKS_NEEDED in legacy platform data, but it's missing from the ti-sysc driver for device tree based configuration. In order to pass OPT_CLKS_NEEDED quirk flag we need to update omap4 module data and add a new compatible for dra7 as the module layout is different from sysc_regbits_omap4_mcasp.
