disp: msm: use connector properties to expose and set panel mode

Expose panel mode from kernel to SDM with SDE connector property
CONNECTOR_PROP_MODE_INFO and set panel mode from SDM to kernel
with SDE connector property CONNECTOR_PROP_SET_PANEL_MODE for
avoiding private change in upstream code in QGKI kernel.
