Use new DRM DSC helpers to setup DSI DSC configuration. The
initial_scale_value needs to be adjusted according to the standard, but
this is a separate change.

Next commits are going to add support for additional RC parameter lookup
tables. These tables are going to use different bpp/bpc combinations,
thus it makes little sense to keep the 2d array for RC parameters.
Switch to using the flat array.

The array of rc_parameters contains a mixture of parameters from DSC 1.1
and DSC 1.2 standards. Split these tow configuration arrays in
preparation to adding more configuration data.

Add a helper setting config values which are typically constant across
operating modes (table E-4 of the standard) and mux_word_size (which is
a const according to 3.5.2).

Create a symlink pointing to USB Type-C connector for DRM connectors
when they are created. The link will be created only if the firmware is
able to describe the connection beween the two connectors.
Currently, even if a display uses a USB Type-C port, there is no way for
the userspace to find whi
Expose DRM connector id in device sysfs so that we can map the connector
id to the connector syspath. Currently, even if we can derive the
connector id from modeset, we do not have a way to find the
corresponding connector's syspath.
This is helpful when determining the root connector of MST tree.

DP 1.4a Section 2.8.7.1.5.6.1:
A DP Source device shall retry at least seven times upon receiving

The drm buddy allocator tests were broken on 32-bit systems, as
rounddown_pow_of_two() takes a long, and the buddy allocator handles
64-bit sizes even on 32-bit systems.
This can be reproduced with the drm_buddy_allocator KUnit tests on i386:
./tools/testing/kunit/kunit.py run --arch i386
The drm_buddy_test KUnit tests verify that returned blocks have sizes
which are powers of two using is_power_of_2(). However, is_power_of_2()
operations on a 'long', but the block size is a u64. So on systems where
long is 32-bit, this can sometimes fail even on correctly sized blocks.
