AMD/Bettong: add FCH's GPIO, UART & I2C support

Hardware / Coreboot - Zheng Bao [gmail.com] - 18 November 2015 10:02 UTC

Merlin Falcon's FCH has GPIO, UART and I2C. All of them are controlled by registers mapped at MMIO space. This ASL code is used for Windows drivers.

TEST: 1. Boot Windows 8 or Windows 10. 2. Install AMD Catalyst driver. 3. AMD FPIO, UART and I2C can be found in device manager. 4. I2C passed Multi Interface Test Tool (MITT) test.
