Continuous splash enabled displays are identified by reading
the MDP ctl registers. DSI cont-splash init settings are
called based on this. Additionally, DSI reads the DSI-CTL
scratch register set by bootloader to detect cont-splash.
This change removes the redundant mechanism in DSI to
detect cont-splash.

Fixes suspend-resume not working after switching dsi clk for
video mode. While switching the dsi clk, FLAG_SEAMLESS_DYN_CLK
is set leading to enable dsi clks which causes extra refcount.

Currently the dynamic bit clock switch trigger for command mode
is supported via sysfs node. This might lead to unnecessary
race conditions, when dsi driver is enabling the dsi bit clock
as part of commit and at the same time if bit rate change via
sysfs happens. So make the trigger happens via kernel mode set
call as done for video mode.

Existing cwb implementation waits for WB done interrupt in
wait_for_commit_done API call. This serializes the cwb commit
and causes frame trigger delay on primary display. MDSS hw allows
to trigger the cwb frame when previous frame is in-progress. This
change updates driver to allow parallel frame trigger for cwb
enabled display. It releases frame N cwb output buffer in frame
N+1 wait_for_commit done call.

The open method for the debug fops are supposed to extract
the appropriate register base for the corresponding
hardware blocks, which are later used for the register
read and writes for the associated hardware block. But
the current open method being used points to some random
register base which can lead to fatal issues when performed
reads and writes to registers. Hence implemented a new
open method to extract the appropriate register base of the
various mdp hardware blocks. This patch also fixes
the valid sub range check against the corresponding
hardware blocks instead of checking across all the hardware
blocks.

Userspace is not supposed to request vblank until crtc is enabled,
because drm framework rejects the request if crtc is not enabled.
Any vblank request prior to that need to be cached in the userspace.

The display driver uses ktime_to_us to timestamp the messages
in the sde event log. But the kernel logs use local_clock to
timestamp the messages. Using same timestamp routine in sde event
log helps to correlate the messages from both the logs
for debug purpose.

Current sde driver allows vblank enable and wait requests
even after crtc is disabled which would eventually lead to
enable of irq and timeouts in caller context. This change fixes
it by updating vblank callback status as 'on' during crtc enable
and shutdowns vblank callbacks before crtc disable is complete.

Currently there is a race condition in checking the
pending_kickoff_cnt in wr_ptr_irq wait from display-thread
and pp_done_irq from interrupt context. In both places,
pending_kickoff_cnt is read first and modified later. In
partial update cases where the frame-transfer is short,
such a race condition might happen and would lead to both
triggering the frame-done/release fence for the same frame.
Fix it by combining read/modify to one statement in both places.
