The current logic for probing ddc is limited to
2 blocks (256 bytes), this patch adds support
for the 4 block (512) data.
To do this, a single 8-bit segment index is
passed to the display via the I2C address 30h.
Data from the selected segment is then immediately
read via the regular DDC2 address
This patch adds support in probing 4 block edid data, for E-DDC.
This is the first test case in CTS, for HDMI compliance.
Changes from V4:
Fix review comments about space and comment indentation.
