Subject: drm/rcar-du: Plug atomic state hooks to the default implementation
Git-commit: dc8c609bd31d2b410fd47a82a7b259f68056b244
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
This is needed to pass a bridge state to all atomic hooks, if we don't
do that, the core can't duplicate/create bridge states.
v10:
* Add changelog to the commit message
v9:
* Add Neil's R-b
* Move earlier in the series
v8:
