drm/radeon/kms/atom: atom parser fixes

Only reset the reg block on the initial execute table call; nested calls require the reg block not be reset on each call. Also reset the fb window and io mode. This matches the upstream parser behavior. Signed-off-by: Alex Deucher <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
