drm/i915: parse VBT general definition block to get the SDVO device info
The general definition block contains the child device tables, which include
the SDVO device info. For example: device slave address, device dvo port,
device type.
We will get the info of SDVO device by parsing the general definition blocks.
Only when a valid slave address is found, it is regarded as the SDVO device.
And the info of DVO port and slave address is recorded.
