Parse the display peripheral related SPMI SID/Peripheral
mask from device-tree and get the dynamic register range
of these peripherals using the SPMI API. These registers
are appended to the list of display IO ranges that is
lent from HLOS to trusted VM during trusted UI. This would
help in adding restrictions for SPMI registers on HLOS during
the trusted UI use case along with validation of the register
ranges in trusted VM.

Added uapi and device_caps changes to enable rotator
compilation and address video device registration failure.
Device_caps field is must for video device registration
unless it is sub device.

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.

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.

This change sets the regulator voltage to zero for all
those regulators which support voltage scaling before
disabling the regulator. Failing to do so causes the regulator
vote to set to the last min value specified in the previous
set voltage call.
Additionally modified the config regulator api and renamed to
get regulator because of the above change.

A new position control register has been added to the DSPP PCC
on Lahaina. This register controls whether PCC is invoked
before or after GAMUT mapping.
Introduce a PCC UAPI flag to indicate if PCC should be placed
before the GAMUT block. By default PCC will be placed after
GAMUT.

Create a new driver to handle sysfs and topology events that are
related to application/userspace layer interactions for HDCP
functionality. In turn, this will create a clear separation from
the HDCP QSEECOM layer that defines the communication mechanism
between the kernel and the TrustZone layers.
This implementation is based on a snapshot of the msm_hdcp
driver as of this commit 10ffbfa2c7e03c09 ("drm/msm/dp: Snapshot
of DP and supporting files") on kernel 4.19 project.
