Add the save and restore for clksrc as part of suspend and resume
so that it saves the counter value and restores. This is needed in
modes like rtc+ddr in self-refresh not doing this stalls the time.
Can't we now do this all in drivers/clocksource/timer-ti-*.c?
arch/arm/boot/dts/am4372.dtsi has compatible ti,omap-counter32k
which is arch/arm/mach-omap2/timer.c compatible
IMHO clocksource suspend resume best fits under mach-omap2/timer.c
just like clockevent has suspend/resume.

Then you can do this based on a quirk flag set by compatible.
