Subject: drm/msm/dpu: add writeback support for sc7180
Git-commit: 51e4d60e6ba50cc53150885549318c3470d44e3c
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
Add writeback support for sc7180 devices. This has been
validated on sc7180 chromebook using IGT writeback test
suite.

Adding this will increase IGT coverage on chromebooks and also
allow using writeback functionality for other use-cases as
necessary.
