[WIP] mainboard: Add Acer ES1-572

Both the Acer Aspire ES1-572 and the Acer Extensa 2540 use the same
mainboard. (Compal LA-E061P)

Tested and working:
- Intel Core i3-6006U with KabyLakeFspBinPkg
- Both SO-DIMM DDR4 slots
- Ethernet
- USB 3.0 port
- HDMI with libgfxinit
- SATA with an SSD
- Loading Linux with SeaBIOS and tianocore
- Power button soldered onto the board's debug pads.
- UART 2 to get yelled at
- S3 suspend and resume, for some reason

Not working or need testing:
- Wi-Fi card. Probably fixed with correct PCIe settings.
- Fan is pretending to be a leaf blower.
- All EC-related stuffs. The thing is an ENE KB9022, similar to KB9012.
- Audio is missing configuration.
- Internal eDP LCD. I think I have the cable somewhere.
- Lid. It was brutally damaged, even though the LCD managed to survive.
- Battery. I have it somewhere.
- Keyboard and touchpad.
- Card reader.
