msm: mdss: fix handling of runtime pm ref counts for fb device

In the current implementation, pm runtime status for the framebuffer
device changes to active when the overlay session is started. With idle
power collapse feature enabled, it is possible that the MDSS core could
be turned off prior to starting the overlay session depending on the
duration of the idle timeout. This may result in an invalid hardware
configuration leading to various target instabilities. Fix this by
holding a reference to the pm runtime when mdp overlay is turned on.
Similarly, when the userspace process is killed, wake up MDSS from idle
power collapse before shutting down the fb device.

msm: mdss: Configure TE GPIO using gpiomux framework

The TE GPIO needed on command mode panels has a gpio_func
value of 1. Acquiring resources of this gpio using gpio_request
API might configure this to a common gpio which has
gpio_func value equal to 0. Hence control this gpio using
the gpiomux framework.

msm: mdss: fix screen shifting in some scenarios when split display enabled

Split display configuration requires that lower and upper pipe
control registers get programmed accordingly. This change fixes
a missing configuration bit in one of the control registers.

msm: vidc: Disable clock gating feature

Clock gating between inter frames when video hardware
is in IDLE state is not giving any power savings and
at the same time this feature is resulting in few
stability issues. So disabling clock gating feature.

msm: mdss: when fb splash logo enabled do not attach iommu

If fb splash logo is enabled pan display gets called with
continuous splash enabled. IOMMU attach should not be called
in such a case as this will lead to IOMMU page faults.

msm: mdss: Fix memory leaks in overlay kickoff

Add missing changes from the commit
398653b3734cd85ee1edd43acf0a11fc03014eb9. That commit is
not propagated properly to LNX.LA.3.6 branch and the
missing changes cause memory leaks during overlay kickoff
in scenarios where it is called without any data input
(i.e. during suspend/resume).

Revert "msm: mdss: handle get buffer failure gracefully"

 * It's possible in the split rotator case for the rotator to
   get queued with has_buf = 0, which results in solidfill being
   enabled on the pipe. This is leads to IOMMU page faults and
   writeback timeouts.
 * Fixes green screen when rotating video on dual-DSI, and 4K
   video rotation on single-DSI (split rotator).

This reverts commit e092ab6793d4c718a37da38f79bb9d79c92c22c8.
