ARM: dts: gemini: add pin control set-up for the SoC
This adds the basic pin control muliplexing settings for the Gemini SoC: parallel (NOR) flash, SATA, optional IDE, PCI and UART. We also select the right GPIO groups on all applicable systems so that GPIO keys/LEDs work smoothly. We can then build upon this for more complex systems.
