[boot-wrapper PATCH 5/5] Rename `CNTFRQ` -> `COUNTER_FREQ`

To avoid any confusuion between the CNTFRQ/CNTFRQ_EL0 register and the
vallue it will be progrmamed with, rename the `CNTFRQ` constant to
`COUNTER_FREQ.

In future patches this will allow us to use `CNTFRQ` as a macro for the
AArch32 CP15 register encoding.

There should be no functional change as a result of this patch.
