[PATCH v3 02/10] drm/bridge: cdns-dsi: Fix the phy_initialized variable

Update the Phy initialized state to "not initialized" when the driver
(and the hardware by extension) gets suspended. This will allow the Phy
to get initialized again after resume.

Fixes: e19233955d9e ("drm/bridge: Add Cadence DSI driver")
