chore(auth)!: remove CryptoCell-712/713 support
CryptoCell-712 and CryptoCell-713 drivers have been deprecated since
TF-A v2.9 and their removal was announced for TF-A v2.10 release.
See [1].
As the release is approaching, this patch deletes these drivers' code as
well as all references to them in the documentation and Arm platforms
code (Nuvoton platform is taken care in a subsequent patch). Associated
build options (ARM_CRYPTOCELL_INTEG and PLAT_CRYPTOCELL_BASE) have also
been removed and thus will have no effect if defined.
This is a breaking change for downstream platforms which use these
drivers.
[1] https://trustedfirmware-a.readthedocs.io/en/v2.9/about/release-information.html#removal-of-deprecated-drivers
Note that TF-A v3.0 release later got renumbered into v2.10.
