target/arm: Mark up sysregs for HFGITR bits 18..47

Mark up the sysreg definitions for the system instructions
trapped by HFGITR bits 18..47. These bits cover TLBI
TLB maintenance instructions.

(If we implemented FEAT_XS we would need to trap some of the
instructions added by that feature using these bits; but we don't
yet, so will need to add the .fgt markup when we do.)
