Help text

Enable workaround for errata 22375 and 24313.

This implements two gicv3-its errata workarounds for ThunderX. Both with a small impact affecting only ITS table allocation.

erratum 22375: only alloc 8MB table size erratum 24313: ignore memory access type

The fixes are in ITS initialization and basically ignore memory access type and table size provided by the TYPER and BASER registers.

If unsure, say Y.
