Giacomo Travaglini d1d90c529c configs: Stop using a PTW cache before L2 in Arm configs ...

This implementation of a walk cache does not allow to skip walks as it
is a simple cache placed in front of the table walker.
It was meant to provide a faster retrieval of page table descriptors
than fetching them from L2 or memory.

This is not needed anymore for Arm as from [1] we implement
partial translation caching in Arm TLBs.
