drm/amdkfd: add debug set flags operation
Allow the debugger to set single memory and single ALU operations.
Some exceptions are imprecise (memory violations, address watch) in the
sense that a trap occurs only when the exception interrupt occurs and
not at the non-halting faulty instruction. Trap temporaries 0 & 1 save
the program counter address, which means that these values will not point
to the faulty instruction address but to whenever the interrupt was
raised.
Setting the Single Memory Operations flag will inject an automatic wait
on every memory operation instruction forcing imprecise memory exceptions
to become precise at the cost of performance. This setting is not
permitted on debug devices that support only a global setting of this
option.
Return the previous set flags to the debugger as well.
