Change adds a check to return a warning rather than an error during a
debugfs read command transfer while the device is suspended.

In ESD register read validation, a for loop is used to increment a
local variable with the length of ESD command. But this is unused
in the validation of the read data. This change removes the unused
for loop.

Fix out of bounds access that occurs when reading dsi
commands with custom non 4 bytes aligned payload.
When misaligned, the code is overfetching data due
to 32 bits reading constraint. This creates an offset
in receiving buffer. Using a local copy buffer large
enough to hold the extra bytes fixes the issue.

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.

When Broadcast is enabled, DMA_DONE bit gets set for slave
controller on command transfer completion but it is not
getting cleared. Due to this, DMA transfer failures on slave
controller are not getting caught. This patch add supports for
clearing DMA_DONE for slave controller on every successful
transfer. This also prints error if transfer fails on slave
controller.

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.
