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 V3: Remove switch,and avoid sending of segment data for non E-DDC Based on drm-next branch Shirish S (1): drm: edid: add support for E-DDC
