msm: timer: Use clockevents_config_and_register()
Don't open code the min/max delta logic. Use the generic
version instead. Also expand the number of bits we can handle
because there isn't anything that says we can't handle all 32
bits.
Before:
max_delta_ns: 122880426391799
min_delta_ns: 122070
mult: 140737
shift: 32
After:
max_delta_ns: 131071523464981
min_delta_ns: 122069
mult: 70369
shift: 31
