Implement clock event driver using low power STM32 timers.
Low power timers counter s running even in when CPU is in stop mode.
It could be used as clock event broadcaster to wake up CPUs but not like
a clocksource because each it rise an interrupt the counter restart from 0.

Hi Linus,

Thanks for your review. I had to rework a bit the driver to solve the
bindings issues
so I haven't put your RB on version 2.

If you have a spare always-on timer (and it looks like you have) which
you can set as free-running, you could register it with
CLOCK_SOURCE_SUSPEND_NONSTOP so it

The driver only implement clock event feature so I don't think that is
flag is applicable.

keeps the system clock ticking also during suspend as
alternative clock source.
