Add downscale blur connector properties to expose the hw block count,
downscaling filters used and the ratios supported. Add a custom dnsc_blur
property to allow usermode to send the required configuration to program
the hardware. Expose only for the virtual connector as the dnsc_blur is
only supported with writeback block.

From Kalama onwards, the VBIF CLK_CTRL register has been moved from TOP block
to individual hardware block memory range.
This change is adding a backward compatible solution to support
per block VBIF CLK_CTRL access by allowing each HW block to register
set of callback ops. Additionally, it adds DMA and IPCC/MSI VBIF CLK_CTRL
block type.

Trusted-vm uses the cont-splash path to initialize the software
states by reading the hardware registers and populating the
SDE & DRM software states. But drm mode cannot be determined by
register reads, so rely on user-mode to get the mode which comes
as part of the first atomic_commit check phase which handles the
transition. The primary-vm user-mode passes the current mode to
trusted-vm through qrtr which is in-turn passed to driver to
set that particular mode.

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.

instead of runtime_pm callback. It works for

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.
