The CGU layout of E825-C is a little different than E822/E823. Add
support the new hardware adding relevant functions.

Simplify the code by using anonymous struct in CGU registers instead of
naming each structure 'field'.

The E822 device has a Clock Generation Unit (CGU) responsible for
determining the clock frequency that drives the timers.
Ensure this function is initialized when bringing up the PTP support, so
that the clock has a known frequency.
