Remove the use of DDC I2C bus bitbang to support reading of EDID

As a result remove the device tree property ddc-i2c-bus.

I think that the dw-hdmi i2c support [1] is a prerequisite of this
patch. I do not see it lands on v4.9-rc1. Or am I missing something?

I'm adding Philipp to Cc, since he is the last one who tested the change
and helped me to push the change to the mainline:

https://lists.freedesktop.org/archives/dri-devel/2016-September/118569.html

The problem is that there is no official DW HDMI bridge maintainer, may be
you can review the change, and if you find it satisfactory push it through
ARM/iMX tree.
