gizmosphere/gizmo2: Changes to make it gizmo2

The preceding patch copied gizmo2 from the amd/olivehill
board. This commit includes the changes required to make
the code reflect the gizmo2 hardware:
  - Update the vendor Kconfig to add gizmo2
  - Update the mainboard Kconfig
  - Update devicetree
  - Add support in for the soldered down DDR3
  - Update the CODEC verb data
  - Update the graphics connector settings
  - Adjust the temperature thresholds for the fan

What's missing:
  - Interrupt routing tables

Gizmo2 can boot DOS and Ubuntu 14.10.
