MIPS: AR7: Add support for Titan (TNETV10xx) SoC variant

Add support for Titan TNETV1050,1055,1056,1060 variants. This SoC is almost
completely identical to AR7 except on a few points:
- a second bank of gpios is available
- vlynq0 on titan is vlynq1 on ar7
- different PHY addresses for cpmac0

This SoC can be found on commercial products like the Linksys WRTP54G

Original patch by Xin with improvments by Florian.
