drm/radeon: Extended DDC Probing for Toshiba L300D Radeon Mobility X1100 HDMI-A Connector

Browse Source 
Toshiba Satellite L300D with ATI Mobility Radeon X1100 sends data
   to i2c bus for a HDMI connector that is not implemented/existent
   on the notebook's board.

   Fix by applying extented DDC probing for this connector.

   Requires [PATCH] drm/radeon: Extended DDC Probing for Connectors
   with Improperly Wired DDC Lines

   Tested for kernel 2.6.38 on Toshiba Satellite L300D notebook
