drm/amd/display: Test link bandwidth readback
[WHAT]
Add KUnit tests for dp_get_link_current_set_bw() covering every link
rate the helper knows about, the unknown rate fallback and the DPCD
read error path.
[HOW]
Add a DPCD backing store for the DSC helpers that is addressed
absolutely, because they read offsets spread across the whole map. A
table driven test then programs the link rate and lane count into the
fake DPCD and checks the returned bandwidth, with one entry arming the
AUX transfer to fail.
