Add an API for force suspending the devices. This API can be
called during unexpected system shutdown/poweroff scenarios
to safely turnoff the devices.

This was only used in a few places just to indirect the already
perfectly valid SYS_CLOCK_TICKS_PER_SEC value. There's no reason for
these to ever have been kconfig units, and in fact the distinction
appears to have introduced a hidden/untested bug in the power
subsystem (the two variables were used interchangably, but they were
defined in reciprocal units!).
Just use "ticks" as our time unit pervasively, and clarify the docs to
explain that.

Add support for adding and selecting pluggable PM policies
which can be enabled based on the application needs.
Also added a dummy policy for demonstration purpose which
simply loops over the supported PM states.
