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