ASoC: omap-mcbsp: Configure wakeup in later phase
Configure the WAKEUPEN register at the same time we configure the rest of the McBSP registers. In case of OMAP3+, if the sysclock has been reconfigured we are going to disable McBSP for the duration of the clock change, which will reset the McBSP registers. The WAKEUPEN register need to be configured later, so the changes will be effective during runtime.
