Hi,
HMP monitor supports printing $register expression. The lookup
was done via GDB stub registers, and supplementary MonitorDef
HMP-specific tables.
Migrate HMP registers to use the GDB infrastructure and remove the
legacy HMP MonitorDef. Use a "qemu-debug" register group, as they are
aliases or synthetic registers, but gdb doesn't seem to care.
Known behavioural changes on RISC-V: CSR lookup is now case-sensitive
and vector registers now report "unkown register" instead of a
target-specific message ("Unable to print the value of vector vreg 'v0'
from this API")
