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

The result is 100 bytes trimmed off the size of a compiled cpmac_get_mac() and as an extra bonus it grumbles and gracefully fails over to using random_ether_addr() when an attempt to parse an invalid MAC address is made.

Move platform specific definitions to the platfrom directories.

Each platform shall do the following:
1) include an entry in arch/mips/Kbuild.platforms
2) add relevant definitions to arch/mips/<platform>/Platform

This commits changes ar7 to the new scheme as an example.

Introducing a platform speecific Platfrom file has following advantages:
1) decentralization of platfrom definitions
2) simplification af arch/mips/Makefile
3) force all platfrom to build with -Werror (done in arch/mips/Kbuild)
