Internal feedback is to exactly match the register dumps
output as it did in execlist, however it seems that the
register dump function in execlist targetting the GT subsystem
also includes non-GT registers like display-related ones that
GuC doesn't manage. So for that, I will have to break up
the execlist function into global-non-gt vs global-gt and then
call the former for both GuC and non-GuC cases (skipping latter
when GuC is doing the dump).
