Some Arm ltd. platforms explicitly set PcdArmArchTimerFreqInHz, however the intended effect of that is not possible from AArch64 EL2/1, and has never been performed unless built for ARM.
The Pcd is now being deleted, so drop the setting. This has however affected timer timout calculations, so could lead to a change in platform behaviour.
