Clocksource to timer configured in pwm mode can be selected using the DT
property ti,clock-source. There are few pwm timers which are not
selecting the clock source and relying on default value in hardware or
selected by driver. Instead of relying on default value, always select
the clock source from DT.

Tony,
This is in preparation with removal of selecting clock source in
prepare() api. Let me know if you prefer separate patches for
each dts.

Thanks Lokesh, with this patch, we should be able to pickup the dmtimer
driver patch to finally allow dmtimer clients to use
assigned-clock-parents.
Once both of these are merged, we can deprecate the ti,clock-source from
the omap-pwm-dmtimer driver.

I've pushed this patch applied against v5.7-rc1 into
omap-for-v5.8/dt-timer.
