TUI clients are the display sub-drivers that participate
during the TUI transition. They register with the display
TUI notification framework with a list of callbacks functions
that will be invoked during pre/post transitions and for quering
I/O memory that need to be access controlled. This change
adds RSC to the TUI client list.
In Trusted VM, all the sub-drivers are not enabled to avoid
any re-configuration of respective module registers. But the
TUI framework need to know the sub-driver I/O memory ranges
in order to accept the I/O memory list lent by the HLOS VM.
So, SDE provides them ranges by reading from a custom
devicetree property.

In the event of panel dead scenario, it is possible to receive a
mode set call before the panel has recovered. When this happens,
display should select watchdog TE as the vsync source.
Similarly when detecting a write pointer timeout, if the panel is
dead then watchdog TE should be or has already been configured and
display should not make a change to this vsync selection.

This change uses kvzalloc to allocate memory for eventlog and register
dumps. This is needed since kernel cannot guarantee that physically
contiguous allocations greater than 32 KB will succeed.
Additionally it reduces the number of entries for evt logs and
register dumps for trusted vm.

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.
