Support 3 new SPE features: FEAT_SPEv1p4 filters, FEAT_SPE_EFT extended
filtering, and SPE_FEAT_FDS data source filtering. The features are
independent can be applied separately:
* Prerequisite sysreg changes - patch 1
* FEAT_SPEv1p4 - patch 2
* FEAT_SPE_EFT - patch 3
* FEAT_SPE_FDS - patches 4 - 7
* FEAT_SPE_FDS Perf tool changes - patches 8 - 10
The first two features will work with old Perfs but a Perf change to
parse the new config4 is required for the last feature.
