arm: zynq: add support for the zybo z7 board

This series adds support for the Digilent Zybo Z7 board

The only think, that I tested, and is not working yet, is reading the MAC address from the OTP region of the SPI flash memory, but I pretend to work on that

I decided to split this series in two patches because the first contains the ps7_init_* file generated by Vivado and is ~170 kB. I tried to strip as much as possible from the file (from ~520 kB), but I wanted to preserve Vivado's comments to compare its output on future versions
(it might have bugfixes).
If the patch doesn't make it to the mailing list, I hope to find another solution, or I'll just simply remove additional content (Vivado's comments)
