Applied to zynq repo.

[U-Boot] [PATCH 6/6] ARM: zynq: Enable EDID for zybo

[Michal Simek]

Zybo contains on board HDMI that's why enable EDID.
Doing it via config because zynq i2c driver hasn't been moved to DM yet
and enabling via Kconfig requires DM_I2C.
This will be moved that driver is moved to DM.

Currently the biggest problem is EEPROM support with DM together.
