Current timeout values in sde driver for vblank, kickoff and
frame complete timeouts are fixed and can be much lower than
a vsync incase of low refresh rate display. Compute timeouts
based on refresh rate for low refresh rate displays.

In the event of panel dead scenario, it is possible to receive a
mode set call before the panel has recovered. When this happens,
display should select watchdog TE as the vsync source.
Similarly when detecting a write pointer timeout, if the panel is
dead then watchdog TE should be or has already been configured and
display should not make a change to this vsync selection.

Remove idle time from the Qsync calculation as this was added by
mistake to allow writes to complete just before the next TE but
this causes tearing. Also, to ensure tearing doesn't recur,
round down the threshold lines to the nearest multiple of 4, and
remove a couple of extra lines to compensate for potential
latencies.

Currently, SDE_DBG_DUMP takes any number of hw block names along with
few defined strings as arguments. This set of arguments is used to
determine which HW block registers needs to be dumped. Move to a
blk bitmask to avoid passing a large set of arguments. The bitmask is
split based on the clks required to access the HW block for ease of use.
The lower 0-23 bits are used for HW blocks which can be accessed by just
enabling the MDP clks. DP is kept separate as it needs DP specific
clks to be enabled. Add a debugfs node through which the mask can be
modified, which can be useful while using the debugfs dump option to
force a panic.
As part of the change, remove in-log/in-mem enable mask debugfs node
for every debugbus and use a single node to control the logging
mechanism for all the HW blocks debugbus.

The SDE RM determines the number of displays enabled in cont-splash by
checking the INTF_ACTIVE bits in the ctl. The trusted-vm relies on the
same cont-splash path during transitions and the stale ctl INTF_ACTIVE
on dual display usecases leads to wrong status check. Currently, only
video/wb encoders use the phys_encoder disable helper during encoder
disable to clear out few ctl/intf registers. Extend it for cmd encoder
as well to remove the stale entries.

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.

VM switches during TUI usecase are expected to be seamless i.e without
display reset. In SDE language, this translates to respective display
drivers not tearing down the HW pipeline while releasing the HW.
In Primary VM, this taken care by keeping the DRM pipeline alive when
TUI is active.
In Trusted VM, since the client creates and destroys the display per
session, checks are needed to bypass the physical encoder disable(s).

To avoid it, during setup of irq_hw_idx, reset the vblank_refcount

maintaining global mutex lock for vblank_refcount.
Also, if register IRQ fails, correct vblank_refcount so
that IRQ registration can be tried again.
