[Why]
Due to the generic introduction of seamless boot, the display is no
longer blanked upon boot. However, this causes corruption on some
systems that does not lock the memory in the non-secure boot case,
resulting in brief corruption on boot due to garbage being written into
the frame buffer.

[How]
Add a flag, read during DC init, to determine whether display should be
blanked on boot. Default to true.

[why]
The current policy will always enable DSC to 12 bpp
regardless of if the current bandwidth is enough for MST displays.
This logic is not optimal because user will get lower quality output
if DSC compression is enabled.
This change to is to implement a DSC MST bandwidth fair share
algorithm so we will dynamically decide if DSC is needed and what
quality (target bpp) is needed to fairly destribute the MST bandwidth
in one MST topology. This will allow user to see the most optimal
image quality with the given bandwidth.

[how]
We will start with lowest bandwidth possible and run a
Max-Min fairness algorithm to fairly distribute the available
bandwidth. If there is still remaining bandwidth, we will try to fit
the timing without DSC compression.

the question "do we support this state", and the rest of it is to determine

[Why]

display_mode_vba is for DCN2 and up. When building for upstream (DCN1
enabled only), there will be a build error, since display_mode_vba.c/h
is stripped out.

Note that building DCN1 only with internal dal-dev is still fine, since
display_mode_vba.h is not stripped out internally - only in upstream.
The make directives therefore stll work, and so will any #include's.

[How]

Since subsequent generations require DCN2 enabled anyways, guard the
makefile directive for display_mode_vba.o with DCN2. Guard any includes
with DCN2. In addition, guard the entire contents of display_mode_vba.h
with DCN2, to simulate the file being stripped out in upstream.

A forward declaration for 'struct display_mode_lib' also needs to be
added in display_mode_lib.h. Previously, display_mode_vba.h contained
the forward declaration, and display_mode_lib.h in turn included it.
This won't work if mode_vba.h is stripped out, requring mode_lib.h to do
so itself.
