arm64: Remove set_cntfrq() function
CNTFRQ_EL0 is a normal AArch64 architectural register like hundreds of
others that are all accessed through the raw_(read|write)_${register}()
family of functions. There's no reason why this register in particular
should have an inconsistent accessor, so replace all instances of
set_cntfrq() with raw_write_cntfrq_el0() and get rid of it.
