b1b8af0443 system: Remove CNTFRQ_EL0 write from arm64 boot 
We don't need this anymore since this is initialized at gem5
construction.

eacc7c7e98 system-arm: AArch64 boot, init CNTFRQ_EL0 
CNTFRQ_EL0 should be initialised to a uniform value in all cores present
in the system. Previously, this was only done if EL3 was present,
however architecture states CNTFRQ_EL0 may be written from the highest
EL implemented.
This patch moves this initilization outside of the EL3-only one.
