clocksource/drivers/timer-microchip-pit64b: Use mchp_pit64b_{suspend, resume}
Use mchp_pit64b_suspend() and mchp_pit64b_resume() to disable or
enable timers clocks on init and remove specific
clk_prepare_{disable, enable} calls. This is ok also for clockevent timer
as proper clock enable, disable is done on .set_state_oneshot,
.set_state_periodic, .set_state_shutdown calls.
