drm/msm/sde: avoid reset on pm_resume during LP1/LP2

Crtc state is left to active when pm_suspend is received
during LP1(doze) or LP2(doze suspend) as the display is still
ON. Avoid resetting the crtc/plane/connectors on pm_resume
when the crtc's are in active state to avoid clearing out
all the states.
