x86: Add support for Intel Minnowboard Max

This is a relatively low-cost x86 board in a small form factor. The main
peripherals are uSD, USB, HDMI, Ethernet and SATA. It uses an Atom 3800
series CPU. So far only the dual core 2GB variant is supported.

This uses the existing FSP support. Binary blobs are required to make this
board work. The microcode update is included as a patch (all 3000 lines of
it).
