mainboard/asus/am1i-a: add support for board ASUS AM1I-A

Add code to support the board ASUS AM1I-A. Tested with multiple payloads
and OSes with satisfactory results. S3 suspend/resume works fine with
Linux but has issues with Windows (an exception is thrown). However,
after manually rebooting, Windows resumes the suspended session.

* Tested with: SeaBIOS 1.11 + Linux 4.10 - OK
* Tested with: tianocore vEDK2017 + MS Windows 8.1 - OK
* Tested with: FILO 0.6.0 - hangs after showing the banner

Details are going to be published on the board's status page.
