Changes since v1:
- The connector .get_modes() operation doesn't rely on EDID anymore,
__ti_sn_bridge_get_edid() and ti_sn_bridge_get_edid() got merged
together
- Fix on top of Sam Ravnborg's DRM_BRIDGE_STATE_OPS
Changes since v2: [Kieran]
- Only support EDID on DRM_MODE_CONNECTOR_DisplayPort modes.
Changes since v3: [Kieran]
- Remove PM calls in ti_sn_bridge_get_edid() and simplify
