Can I update the commit message to this?

Add code to retrieve the reset property from the dw-apb timers and if
the property is available, the safe operation is to assert the timer
into reset, and followed by a deassert of the timer reset(brings the
timer out of reset).

This patch is needed for systems where the bootloader has left the timer
not used in reset.
