ArmPkg: drop manual ARM programming of generic timer frequency
There is a bit of legacy code in ArmArchTimerLib that attempts to program
the generic timer based on a Pcd. This was only ever done for (32-bit)
ARM in case the cpu lacked the Security Extensions (because if they were
there, Secure firmware would be expected to have configured this before
switching to Non-secure state).
We don't support operation without Secure firmware anymore, but also the
code has been incorrectly invoked only on platforms that *do* implement
the Security Extensions since December 2020 and commit 0dd0d42ab5b6
("ArmPkg: use helper to check for Security extensions in ArmArchTimerLib")
As a result, edk2 has been overriding any programming done by Secure
Firmware on ARM platforms. Which is wrong.
Drop this programming in preparation for deleting the Pcd completely.
