Subject: [PATCH 44/47] arm64/sysreg: Add remaining debug registers affected by HDFGxTR2_EL2

The HDFGxTR2_EL2 registers trap a set of debug and trace related registers.
Almost all of those register encodings have been added in the tools sysreg
format. Let's also add all the remaining encodings which are formula based
(and only that, because we really don't care about what these registers
actually do at this stage).
