[PATCH 19/23] target/arm: Mark up sysregs for HFGITR bits 48..63

[Peter Maydell <peter.maydell@linaro.org>]

Mark up the sysreg definitions for the system instructions
trapped by HFGITR bits 48..63.

Some of these bits are for trapping instructions which are
not in the system instruction encoding (i.e. which are
not handled by the ARMCPRegInfo mechanism):
 * ERET, ERETAA, ERETAB
 * SVC

We will have to handle those separately and manually.
