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.
