The MEM & IRQ lend handlers signals the resources
are lent from the primary VM. Reserve the SDE HW
resources in trusted VM using the cont-splash path
and setup the SDE & DRM software states. Set the
DSI connector status to active for the handoff
display during the start and disable it at the end
of the session.

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.

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.

Vblank refcount can reach out of sync with below case
1. event_thread triggers the vblank_enable
2. commit_thread triggers the modeset
2.a modeset resets the vblank refcount with mode_set
3. event_thread triggers the vblank_disable
Event 2.a resets the vblank refcount and vblank disable
request after 2.a is going to fail. This can be fixed
by avoiding concurrency between mode_set call and vblank
request.

Treating hw version as a signed int results in a negative
number when major version is more than 7, leading to errors
when comparing versions in the driver. Fix this by making
sure all HW version definitions and variables are unsigned.

Video mode display keeps the MDP clocks in ON state but
disables irq during static screen to avoid cpu wakeup.
In such case, CPU pm_qos vote should also be removed
to allow LPM transition. This change triggers the
pm_qos vote based on mdp interrupt enable counts
instead of runtime_pm callback. It works for
multi-display concurrency also.

Add a QoS vote on CPU receiving display interrupt. QoS vote
will prevent that CPU from going into low power mode avoiding
possible interrupt latency. Using irq notifier, display will
receive notification when display IRQ has switched CPUs and
will adjust the vote accordingly. The vote is also removed and
requested whenever display IRQ is enabled or disabled.

In Dual display concurrencies there are certain cases where
irq_idx and vblank_refcount state mismatch can occur.
To avoid it, during setup of irq_hw_idx, reset the vblank_refcount
and unregister read ptr irq if not yet done by then along with
maintaining global mutex lock for vblank_refcount.
Also, if register IRQ fails, correct vblank_refcount so
that IRQ registration can be tried again.

During secure-ui, the SMMU, MISR and VBIF states
are altered based on the enable/disable of secure-ui
which is followed by the scm_call. Failure in any of
the steps would lead the system to an unstable state.
Address all the failures and revert back all steps
to get the system back in original state to avoid
any issues.
