msm: mdss: dsi: fix the check for PLL off when turning off PHY
Current implementation checks for the DSI PLL to be off prior to
shutting down the DSI PHY, and reports a warning if the PLL is
still detected to be on. However, this check is incorrectly
implemented resulting a false warning being printed every time
the display is turned off. Fix this by reading the right set of
registers to check for the PLL status.
