In ESD register read validation, a for loop is used to increment a
local variable with the length of ESD command. But this is unused
in the validation of the read data. This change removes the unused
for loop.

Add support to use atomic variable instead of spinlock
for register logs during register write. This change
helps in reducing the run-time and is safe to use as
most of the register writes happen in commit context.

Replace the DSI_DEBUG logs with pr_debug logs for backlight related
color processing features. DSI_DEBUG logs cannot be enabled dynamically
by the /sys/kernel/debug/dynamic_debug/control sysfs node, hence move to
pr_debug instead.

The connector detect function is currently implemented as a
callback from the framework, and creates a context before
calling the detect_port_ctx MST callback. This change updates
the callflow so that the framework calls the new detect_ctx
function in the MST case. This removes the need for creating a
new context before calling further downstream functions.
In addition, references to the mst_connector_get_info
function were replaced by connector_get_info to avoid
redundancy.

This change allows signalling of sde fences when sequence number is
less than done_count. In current scenario, fence is not signaled as
the subtraction result is not typecasted to int before updating
the status causing the UI thread to block on sde fence.

During mode enable after idle, rsvp next would be be set without
rsvp cur. Back to back test only should be serialized, but currently
this would be possible right after idle. This is established by
commit 11aab5f9c3 (disp: msm: sde: Fix null dereference errors).
This change updates the condition to poll for rsvp next clear
during this usecase as well.

Fix out of bounds access that occurs when reading dsi
commands with custom non 4 bytes aligned payload.
When misaligned, the code is overfetching data due
to 32 bits reading constraint. This creates an offset
in receiving buffer. Using a local copy buffer large
enough to hold the extra bytes fixes the issue.
