samsung/exynos5: add resource functions for the display port
This does NOT turn on the graphics.
The device tree has been changed enough so that, at the very least, the correct
functions are called at the correct time, with the correct paramaters. We
decided to yank the I2C entries as they did not obvious function and might
not even have been correct.
Not working, seemingly, but we need to add a 4M resource for
memory, and it seems it needs to be fixed at the address shown.
This address was chosen from current hardware.
We realized that the display code should be part of the cpu -- that's how
the hardware works!
