-Subject: [PATCH 1071/1110] drm/amd/dal: change default to use SW i2c
-
-Make SW i2c engine the default. However, since all dces except
-dce80 do not create sw i2c engine, they will still use hw i2c.
-This allow enabling/disabling of sw i2c through the feature flag
-FEATURE_RESTORE_USAGE_I2C_SW_ENGINE. DCE80 is the only dce that
-has sw i2c engine enabled right now due to bug in hw i2c. This
-fixes EDID read failure on bonaire. No behaviour change on other
-dces.
