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.

This change moves the DSC implementation into a separate file.
This is required to add support for new compression algorithms.
This cleanup change also, moves struct sde_encoder_virt
declaration to the encoder header file.

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.

This change saves the previous state before moving into the transitional
smmu state, during secure-display/secure-camera usecases. Upon failure
to complete the transition, set smmu state to the previous state.
Previously, smmu state was staying in transitional state.

when the LTM sw fuse is set to enable.

Add runtime_pm ops support in drm driver instead
of direct sde_power_resource_enable/disable call.
It allows drm driver to use runtime pm refcount logic
to track the resources instead of custom implementation.
The change also removes the NRT_CLIENT support from
sde_power_handle code to simplify it further.
