X-Git-Tag: v3.19-rc1~73^2~64^2~94

drm/i915/audio: set ELD Conn_Type at one place

Keep the driver modifications to ELD together. This also sets the
Conn_Type for G4X DP which wasn't done before.

Clean up the debugs while at it; this is all obvious from the connector
name.

v3: add missing ~ (Rodrigo)
