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 using a repeated I2C 'START' signal.
