During ESD check failure, DSI video engine can get stuck
sending data from display engine. In use cases where GDSC
toggle does not happen like DP MST connected or secure video
playback, display does not recover back after ESD failure.
This change adds support to perform soft reset when DSI
video engine gets stuck.

This change allows dynamic refresh trigger to sw trigger
and mdp intf flush. With this we can make sure that DSI
timing/clock update and mdp intf timings are updated in
one vsync.

The change adds register mapping of MDP_INTF_[1/2]_TEAR_INT_COUNT_VAL
register to DSI controller. This allows for the controller to read the
line count and frame count of the read pointer during trigger and
successful transfer of DMA command.
To enable the debug feature:
echo 1 > /d/<panel_name>/dsi-ctrl-0/enable_cmd_dma_stats.
To disable the debug feature
echo 0 > /d/<panel_name>/dsi-ctrl-0/enable_cmd_dma_stats.
To read line count value:
cat /d/<panel_name>/dsi-ctrl-0/cmd_dma_stats.

The change allows for configuring a command DMA window during which
the command is triggered. The DMA window must not intersect with the
MDP tear check window. Once the command transfer is successful, the
trigger control needs to reset to the default DMA trigger specified
by the panel.

Avoid sharing and have dedicated dsi HW ctrl ops across versions
even if they are identical. It helps to stub out a specific
version of ops if needed.

From Lahaina onwards, for compressed DSI output, widebus should be enabled.
In widebus mode, 6 bytes of data are transmitted per pclk.
For uncompressed output, widebus must be disabled to transmit 3 bytes
of uncompressed data per pclk.

Move DSI debugbus dumping logic from DSI driver to sde_dbg
in order to utilize the framework in place for debugbuses.
This allows for more control over the dumping logic, such
as where the dump data is stored(memory/console), via nodes
populated in debugfs.

Continuous splash enabled displays are identified by reading
the MDP ctl registers. DSI cont-splash init settings are
called based on this. Additionally, DSI reads the DSI-CTL
scratch register set by bootloader to detect cont-splash.
This change removes the redundant mechanism in DSI to
detect cont-splash.

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.
