Add missing compatible strings from 4.9/960-add-rasbperrypi-compatible.patch, using upstream names for compute modules. Add extra patch to enable the LEDs on lan78xx.

Subject: [PATCH 349/454] drm/vc4: Fix oops dereferencing DPI's connector since
|
|
panel_bridge.
|
|
|
|
In the cleanup, I didn't notice that we needed to dereference the
|
|
connector for the bus_format. Fix the regression by looking up the
|
|
first (and only) connector attached to us, and assume that its
|
|
bus_format is what we want. Some day it would be good to have that
|
|
part of display_info attached to the bridge, instead.
|
|
|
|
v2: Fix stray whitespace change
