KVM: arm64: Support trace filtering for guests
For nVHE, switch the filter value in and out if the Coresight driver
asks for it. This will support filters for guests when sinks other than
TRBE are used.
For VHE, just write the filter directly to TRFCR_EL1 where trace can be
used even with TRBE sinks.
