Replace the DSI_DEBUG logs with pr_debug logs for backlight related

by the /sys/kernel/debug/dynamic_debug/control sysfs node, hence move to

At present, the sim panels and physical panels booting up as sim
panels have a call flow issue causing reset gpio to be set in the
panel reset sequence even without valid reset gpio. This causes
GPIO warnings as it tries to set value for invalid reset GPIO.
The following change fixes these GPIO warnings, by checking
valid reset GPIO before setting value.

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 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

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
