Add writeback support for sc7180 devices. This has been validated on sc7180 chromebook using IGT writeback test suite. localhost /usr/local/libexec/igt-gpu-tools # ./kms_writeback Starting subtest: writeback-pixel-formats Subtest writeback-pixel-formats: SUCCESS (0.001s) Starting subtest: writeback-invalid-parameters Subtest writeback-invalid-parameters: SUCCESS (0.004s) Starting subtest: writeback-fb-id Subtest writeback-fb-id: SUCCESS (0.009s) Starting subtest: writeback-check-output Subtest writeback-check-output: SUCCESS (0.203s) Adding this will increase IGT coverage on chromebooks and also allow using writeback functionality for other use-cases as necessary.
