drm/msm: fix sde debug bus test point for valid status 



SSPP0/SSPP1/PERIPH debug test macro status is updated
to DSPP debug status register. This test point won't
capture the test point status if DSPP test point is
not enabled with valid setting. This patch fixes the
SSPP0/SSPP1/PERIPH debug test point status.
