aarch64: Add support for debugging in HYP mode on ARMv8-A cores
When debugging an ARMv8-A/AArch32 target running HYP mode, OpenOCD would
throw the following error to GDB on most operations (step, set breakpoint):
cannot read system control register in this mode
The mode in question is 0x1A, a privilege level 2 mode available on cores
that have the virtualization extensions (such as the Raspi 3).
Note: this mode is only used when running in AArch32 compatibility mode.
