Change overrides the panel physical dimensions with correct
value upto a precision of millimeter, which was getting
truncated to centimeter as drm structures maintain it in
centimeters.

Change adds flag to identify dynamic mode switch with same
resolution and different fps. Block sending PPS command
if we hit this scenario, this optimizes mode switch time.

This change moves the panel null check to the beginning of the function
so panel can be used throughout the function. This change also replaces
looping through display ctrls with proper display_for_each_ctrl.

DSI driver sends nolp commands when DSI connector power
modes is set SDE_MODE_DPMS_ON or SDE_MODE_DPMS_OFF. This
is invalid panel configuration. It should only send nolp
commmand to panel when it is in LP1/LP2 mode.

Minimum threshold time is sum of panel jitter time, prefill lines time
and buffer time of 100usec. For panels with high jitter, we can cross the
default threshold time. Update the calculation to accommodate high jitter
