[WHAT & HOW]
misc0, temp and split_pipe are assigned but immediately re-assigned
to other values. The early assignments are useless and are removed.
Unused variables are removed as well.
This fixes 5 UNUSED_VALUE issues reported by Coverity.

[Why]
For some EDP to MIPI panel, disabling OTG when link is alive like boot
case, the converter might output garbage or show no display because our
GPU is not sending required pixel data.
Alos Dig fifo underflow was found which might cause garbage, when
resetting otg for other types of EDP panels.
[How]
Skipping resetting OTG if the dig fifo is on. Make sure that the otg for
the pipe is the one that the dig fifo is selecting via the FE mask.

[Why]
When pre-OS firmware enables display support for displays that operate
the DIG in 2 pixels per cycle processing modes the inferred pixel rate
from get_pixel_clk_frequency_100hz does not account for the true pixel
rate since we're outputting 2 per cycle past the stream encoder.
This causes seamless boot validation to abort early.
[How]
Add a new stream encoder function for getting pixels per cycle from the
stream encoder. If the pixels per cycle is greater than 1 and the driver
policy is to enable 2 pixels per cycle for post-OS then allow seamless
boot to continue.

[Why]
This is a workaround for an dcn3.1 hang that happens if otg dispclk
is ramped while otg is on and stream enc is off.
But this w/a should not trigger when we have a dig active.
[How]
Avoid disable otg when dig FE/BE FIFO was not switched.

[why]
Move DCN3X files to unique component folder.
[how]
Create respective component folder in dc, move the DCN3X files into
corresponding new folders and made appropriate changes for compilation
in Makefiles.
