This operation allows the debugger to override the enabled HW
exceptions on the device.
On debug devices that only support the debugging of a single process,
the HW exceptions are global and set through the SPI_GDBG_TRAP_MASK
register.
Because they are global, only address watch exceptions are allowed to
be enabled. In other words, the debugger must preserve all non-address
watch exception states in normal mode operation by barring a full
replacement override or a non-address watch override request.
For multi-process debugging, all HW exception overrides are per-VMID so
all exceptions can be overridden or fully replaced.
In order for the debugger to know what is permissible, returned the
supported override mask back to the debugger along with the previously
enable overrides.
v2: switch unsupported override mode return from EPERM to EINVAL to
support unique EPERM on PTRACE failure.
