Add VM layer files to handle VM specific operations
for primary and secondary VM's. They interact with
Hypervisor RM modules to LEND/ACCEPT/RELEASE/RECLAIM
HW resources. They also handle notifications for each
of the above Hyp RM operations to acquire and update
the SDE software states.

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.

Trusted VM will be granted access to MDSS HW dynamically on
usecase boundary. As a result, all the attempts to access
HW before the assignment, including the probe time access
will result in Stage 2 faults. This change skips the
PLL clock registration during probe as the clocks will not
be controlled by the VM.

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.

Besides SDE, other subdrivers may be interested in participating in
the VM switch. This change provides framework for display dependent
drivers like DSI, DP and RSCC to register for various VM switch
event hooks.
The following hooks to provided through msm_vm_ops:
post_hw_acquire: invoked before the first frame push after gaining
HW access.
pre_hw_release: invoked after the last frame commit before releasing
the HW.
check: check with vm clients for their readiness for HW
releasing.

Currently during CRTC atomic check phase, driver is counting
the number of connectors attached to the CRTC by iterating over
all the connectors available and checking if they are attached
to the CRTC. The current implementation uses the old connector
state, which has an invalid state for the first commit. This
causes the number of attached connectors to always be 0 for the
first commit.
This change extracts the new connector state from the atomic state
and ensures the calculation is done before checking crtc features.
