drm/bridge: dw_hdmi: support i2c extended read mode
"I2C Master Interface Extended Read Mode" implements a segment
pointer-based read operation using the Special Register configuration.
This patch fix https://patchwork.kernel.org/patch/7098101/ mentioned
"The current implementation does not support "I2C Master Interface
Extended Read Mode" to read data addressed by non-zero segment
pointer, this means that if EDID has more than 1 extension blocks,
EDID reading operation won't succeed"
With this patch, dw-hdmi can read EDID data with 1/2/4 blocks.
