DSI driver stubs out GPIO parsing in trusted vm. Add support
for ESD trigger in trusted vm by explicitly parsing the
reset gpio and setting the value.

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.

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.
