mainboard/bap/ode_e21XX: Add board support

Add next generation of BAPs (https://www.unibap.com/) SOC module,
called ode_e21XX.
Hardware is similar to e20XX (AMD G-Series GX-411GA Kabini),
but it includes a new AMD G-Series GX-412HC (Steppe Eagle)
and an updated Microsemi FPGA.
Changes to Olivehillplus:
- Add SuperIO Fintek F81866D
- Soldered down DDR3 with ECC
- User can choose between different DDR3 clk settings
(lowest setting can save up to 1.2W)
- Soldered down Microsemi M2S060 FPGA on PCIe lanes 2-3

Tested with:
- Payload SeaBIOS 1.9.1
- Lubuntu 16.04, Kernel 4.4.0
- Windows 10 (UART functionality)
Known problems:
- S3 not working
- IOMMU not working
