The order of the panel timing nodes specified in the device tree is
not guaranteed to be the same while being parsed in the driver. This
results in unintended modes being set as preferred timing mode. The change
introduces cell-index property, so that the timing modes can be
accurately indexed and parsed.

Currently, RFI feature only supports panel that contains
a single timing node. This limits the feature availability
for panel with multiple modes or with DFPS support.
This change adds support for RFI on panels that contains
multiple timing nodes.

Add a new connector range property and a new entry to the panel
capability blob to publish the list of supported RFI frequencies.
In addition, add the required functions to set, validate and update
DSI bit clock rate value to trigger an internal seamless mode switch
and reconfigure DSI clock and PLL.

Currently, a different dsi_display_mode is created for
each combination of RFI frequency, but only one of
those modes is reported to the user. Hence,
it is not necessary to create multiple RFI modes anymore.
This change removes code to inflate the list of modes
by the number of RFI frequencies, removes pclk from
the mode name as it will change dynamically.

Use of drm_display_mode vrefresh is being deprecated in
upstream DRM framework. Downstream driver need to use
drm_mode_vrefresh API from now on.
This change removes dependency on drm_display_mode vrefresh
and replaces it with drm_mode_vrefresh API in SDE, DSI and
DP driver. In addition, it also modifies drm_display_mode clock
to align with upstream approach where an uncompressed mode clock
is required to match drm_mode_vrefresh API.

This change moves the backlight update operation from
drm bridge enable to connector post kickoff.
When timing engine is enabled with programmable fetch
enabled, the timing engine will start counting from
the prog_fetch_start point (which is somewhere in VFP).
It’s a grey area from that point to the actual panel
vsync and SW should not trigger DMA command during that
time.
During display resume, sometimes the INTF timing engine
do not get enabled completely at the first vblank irq.
The backlight update cmd transfer trigger as part of the
drm bridge enable can also take place at the same time,
that may cause DSI cmd transfer failure.

As per the HW requirements it is highly recommended to use DMA start
window to trigger broadcast commands. If not used then it can
result in a hardware hang with the DSI controllers going out
of sync. This behavior is even more prominent in cases of higher
refresh rates. As part of the change we change the default DMA
scheduling behavior to default to maximum possible DMA window
in case it is not specified in the panel device tree.

It is not applicable for all DFPS cases to update UIDLE state
according to current frame rate. If DFPS changes frame rate
through vertical front porch values, the SDE clocks and transfer
time will not get changed accordingly, and it always get fixed
at max frame rate configuration of DFPS.
Add this change to check max FPS of DFPS instead of current
frame rate for UIDLE update, if DFPS is enabled with VFP.
