target/arm: Implement FEAT_HPDS2 as a no-op

Browse source 
This feature allows the operating system to set TCR_ELx.HWU*
to allow the implementation to use the PBHA bits from the
block and page descriptors for for IMPLEMENTATION DEFINED
purposes.  Since QEMU has no need to use these bits, we may
simply ignore them.
