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.

* tag 'omap-for-v4.21/driver-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
soc: ti: wkup_m3: Add PRCM int16 as the wake up source
bus: ti-sysc: Detect devices for debug on omap5
bus: ti-sysc: Add mcasp optional clocks flag
bus: ti-sysc: Fix getting optional clocks in clock_roles
