With the new design of moving clock voting and command engine state
transition to DSI controller APIs, asynchronous wait after a command
transfer can now be supported on video mode panels.

To transfer a command on the DSI lanes, the following programming needs
to happen prior and post a command transfer:
- Vote/Unvote for clocks
- Enable/Disable command engine
- Mask/Unmask overflow and underflow errors.
These operations are done from the display context currently. This can
lead to issues during an ASYNC command wait, where in we queue the
dma_wait_for_done rather than wait in the same display thread.
The following change adds new DSI controller API that does the above
programming from the controller context. This way, post command transfer
operations can only happen once command is successfully transferred and
dma_wait_for_done completes.

Currently on video mode panel, when the RFI bit clock
rate is set back to the default rate, the driver is not
detecting that a VRR operation is necessary due to
unchanged porches value.
This change is forcing a VRR update on video mode panel
whenever the RFI bit clock rate is changed.

Currently, on a video mode panel when a mode switch occurs after the RFI
bit clock rate has been changed, the driver fails to find the new mode
in the list of panel modes due to different porches value between
the adjusted mode and the default panel mode.
This change removes the front and back porch value check from mode
matching function when dynamic bit clock and maintain constant FPS
features are enabled.

Request for display in firmware only if no display enabled form
the UEFI.
In the targets supporting dual DSI display having both displays
DT nodes part of the connector list, if only one display is
enabled from the UEFI, then the driver requests for display
in firmware for the second display. Getting the display panel node
from firmware is time taking process, and it can take up to
ten seconds. This causes a delay in adding the component for the second
display, resulting in a delay in bind calls for components of the
msm drm driver.

DSI display configuration can be either DT or firmware file driven.
When probed with firmware path, asynchronous firmware file read
callback function will be too late to check for dependencies and
defer the probe when the dependencies are not met.
Move all the dependency checks before the firmware file read request.
Since the panel data will not be available before the DT/firmware read,
this change limits the check to the dsi display layer.

Clients of dsi driver can register to be notified of panel id
information. Dsi is probed early during the device boot-up. If the panel
id is available with dsi driver none of the clients have registered

panel id is not passed onto clients until power on of the dsi. Change
