Peter Maydell ad140dadd5 ptimer: Add new ptimer_set_period_from_clock() function 
The ptimer API currently provides two methods for setting the period:
ptimer_set_period(), which takes a period in nanoseconds, and
ptimer_set_freq(), which takes a frequency in Hz.  Neither of these
lines up nicely with the Clock API, because although both the Clock
and the ptimer track the frequency using a representation of whole
and fractional nanoseconds, conversion via either period-in-ns or
frequency-in-Hz will introduce a rounding error.

Add a new function ptimer_set_period_from_clock() which takes the
Clock object directly to avoid the rounding issues.  This includes a
facility for the user to specify that there is a frequency divider
between the Clock proper and the timer, as some timer devices like
the CMSDK APB dualtimer need this.

To avoid having to drag in clock.h from ptimer.h we add the Clock
type to typedefs.h.
