Power handle API stores the clocks dt parsing return
code in to an "unsigned integer" while of_node API
may return an error code if clocks are not present
in dtsi. That may lead to invalid memory allocation
also. This patch fixes the clock parsing and avoids
free if clocks are not allocated.

The driver should utilize the ktime_ series of functions to directly
manipulate the time structures rather than converting everything to
nanoseconds. This avoids possible trunction/rounding errors that may
be introduced by the conversion process.

This change modifies the module name to something that's more
specific to DRM support for msm to minimize the possibility of
name clashes with other msm drivers.

CRTC's are created for each display and require a dedicated primary
plane for non-atomic operation. Atomic callflows don't have this
requirement and allow for any plane to be used with any CRTC, as
long as the driver can support it.
This change optionally resets each plane's possible_crtcs bitmask to
allow it to be used by other CRTCs as well.
This allows the driver to work with both atomic and non-atomic
callflows as long as non-atomic clients respect each plane's
advertised primary/overlay type.

so limit the number of planes flagged as 'primary' to the max

Need to teardown all active crtcs during lastclose to avoid
causing faults by turning off clocks on running hardware. To
do this, implement the lastclose handler, and have it send in a
disabling commit for all planes and crtcs. To support this,
need to move the clock enable / disable out of the device open
and close handlers, and into the use case enable / disable in
the encoder, and into the vblank enable / disable handlers. As
well, needed to remove fence refcounting logic from duplicate
state function since the fd at that time is not valid, and the
ref counting itself is unnecessary.

Crtc atomic check is updating zpos of current plane state. This
would corrupt current plane state if the atomic check is initiated
by test only atomic commit. In that case, the test only update
would propgate to current state incorrectly.

zpos update.

Blob properties under DRM require a new blob to be created for
each unique set of incoming data. By changing the scaler property
to accept an incoming user space pointer and using copy_from_user
to explicitly copy out the structure data each time the property
is set, the user space client avoids the need to create new
DRM blob objects when the scaler config needs to be updated.
