Driver changes for omaps for v4.21 merge window

Few SoC related driver changes to add PRCM as the wake-up source
for wkup_m3_ipc driver, and to improve ti-sysc driver for dra7
mcasp and device detection when debug is enabled.

There is also a non-critical fix for ti-sysc to fix handling of
the optional clocks but this can wait for the merge window no problem.
