With this change, mdp transfer time updated to userspace
will be the preferred dtsi entry, when both dsi clock
and mdp transfer time nodes are set.

ELVDD/ELVSS has a dip during AMODE panel AOD exit hand-off.
According to PMIC team's suggestion, need to config the AB/IBB power
to REGULATOR_MODE_IDLE/REGULATOR_MODE_NORMAL to fix dips.

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
panels in calculating dsi clocks.

Currently the dynamic bit clock switch trigger for command mode
is supported via sysfs node. This might lead to unnecessary
race conditions, when dsi driver is enabling the dsi bit clock
as part of commit and at the same time if bit rate change via
sysfs happens. So make the trigger happens via kernel mode set
call as done for video mode.

This change adds support for dynamic switching of dsi clocks
to avoid RF interference issues. Also with dynamic dsi clock
switch feature coming into picture, now populate the supported
refresh rate as list instead of providing a range. Modify the
logic to enumerate all the modes in dsi driver, taking dynamic
bit clocks, resolutions and refresh rates into account.
