Rahul Rameshbabu c066e74f34 ptp: ptp_clockmatrix: Add .getmaxphase ptp_clock_info callback 
Advertise the maximum offset the .adjphase callback is capable of
supporting in nanoseconds for IDT ClockMatrix devices. Depend on
ptp_clock_adjtime for handling out-of-range offsets. ptp_clock_adjtime
returns -ERANGE instead of clamping out-of-range offsets.
