mainboard/intel/minnowmax: Add MinnowMax mainboard

MinnowMax board using Intel's Bay Trail FSP

Working:
- Booting from SATA / USB / (USB3 with latest SeaBIOS)

Not working:
- Boot from SD
- S3 Suspend / Resume

***** To configure the FSP *****
Download the Bay Trail FSP and the binary config tool:

Modify the standard Bay Trail FSP:
run the bct tool with the command line options:
bct --bin <Bay Trail FSP Binary> \
	--absf src/vendorcode/intel/fsp/baytrail/absf/minnowmax_Xgb.absf \
	--bout <path to save the updated FSP to>

Here are the required changes for modifying the FSP manually:
	Enable Memory Down: Enabled
	DRAM Speed: 1066 MHz
	DIMM_DWidth: x16
	DIMM_Density: 4 Gbit (2GB Minnow Max) / 2 Gbit (1GB Minnow Max)
	tCL: 7
	tRP_tRCD: 7
	tWR: 8
	tRRD: 6
	tRTP: 4
	tFAW: 27
Other FSP values can remain the same.

***** To configure the vbios *****
The vbios is in the Bay Trail FSP package.
Download Intel's "Binary Modification Program" (BMP)
Use it to disable all ports except HDMI on port B.
