Use MDP scratch registers to pass drm mode index information

the current mode for all active displays before handoff.
LE VM relies on this information to set the corresponding

clients to register for callbacks to be invoked
- before releasing the resources from the current VM so that
the client can updates the respective sw state to indicate

- before the first frame push after acquiring the HW to update
reset the respective sw state to indicate the presence of
HW ownership and resume operations

Commit d46cae019e ("disp: msm: sde: trigger pm_qos vote
with irq enable") moves the pm_qos vote with irq
enable/disable state. Such irq enable/disable call may be
triggered from atomic context and lead to scheduling issues
due to mutex_lock usage in pm_qos APIs. This change moves
the vote with encoder idle pc to allow lock usage with sleep.

Display in trusted VM works in a handover mode i.e, all
display components need to be initialized by the primary VM
before switching to trusted VM on the usecase boundary.
That makes it a hard requirement for the trusted VM not to
re-program any of the display configuration registers before
it could hand the HW back to the primary VM.
Also, most of the linux framework drivers including pintrl, clocks
are not enabled in the trusted VM.
In order to address the above two limitations and to control the
probe/commit sequences, this change adapts the same path as that
of continuous splash to bypass some of the critical functions
which are identified to be HW intrusive. Based on the DT property
read from SDE handle, dsi drivers will choose to bypass
enable/disable HW state updates when executing in the vm environment.

When the TUI use case starts, HLOS prepares for sharing the HW
by collecting the register io spaces and IRQ lines from all the
participating subdrivers before the switch. This change
adds necessary hook in the VM event framework, so that
subdrivers can provide their callback functions while
registering for events. It also adds necessary helpers
in the sde io util to parse and populate the IO memory
region that needs to be shared.

MST simulation ports can be removed either through HPD unplug, which
removes all ports on the branch device or through hpd irq, which
removed individual ports. In the current driver, the mst state
on the topology manager is being cleared prematurely. This results
in incorrect port status values being reported when the usermode
queries the status prior to disabling the corresponding displays.
So in its current state, on a HPD unplug, the display is disabled
but the port objects are not cleaned up and new ports are added
on every replug. On hpd irq, not all references are removed on
the port object and also the connectors are prematurely being
removed from the connector list. Additionally, when the last
port is removed, the mst state is cleared on the topology manager,
which destroys the branch device. Once the branch device is
destroyed, the ports cannot be added anymore and this leaves the
MST driver in an invalid state.
This change adds a new helper to remove the port and update the
connector list. It also moves the clearing of mst state to hpd
disconnect callback where the branch device can be safely destroyed.
