[Intel-gfx] [PATCH 0/3] use the sdvo device info parsed from VBT to initialize SDVO device

[yakui_zhao]

Hi, 
        The following is the patch set that use the SDVO device info
parsed from general definition block to initialize the SDVO device.
        By parsing the general definition block of VBT we can get the
relationship between the DVO port and slave address. For example: the
SDVO wiring, the SDVO slave address. And then we use the info to
initialize the SDVO device. If the slave address can obtained for SDVO
port(SDVOB/SDVOC), it will be initialized correctly. If no slave address
is found for the SDVO port, it won't be initialized.
        
	Patch 01/3: Dynamically get the number of child device in general
definition block
        Patch 02/3: parse general definition block to get the SDVO
device info.
        Patch 03/3: Initialize the SDVO device based on the the sdvo
device info parsed from general definition block

Welcome the comments.
