ARM platforms: Initialize cntfrq for BL1 Firmware update

Currenly the CNTFRQ register and system timer is initialized in BL31 for
use by the normal world. During firmware update, the NS-BL1 or NS-BL2U
may need to access the system timer. Hence this patch duplicates the
CNTFRQ and system timer initialization in BL1 as well.
