Andrew Bradford f3b84a3032 x86: baytrail: Configure FSP UPD from device tree
Allow for configuration of FSP UPD from the device tree which will
override any settings which the FSP was built with itself.

Modify the MinnowMax and BayleyBay boards to transfer sensible UPD
settings from the Intel FSPv4 Gold release to the respective dts files,
with the condition that the memory-down parameters for MinnowMax are
also used.

Intel Bay Trail FSP UPD Binding
===============================
The device tree node which describes the overriding of the Intel Bay Trail FSP
UPD data for configuring the SoC.
All properties can be found within the `upd-region` struct in
arch/x86/include/asm/arch-baytrail/fsp/fsp_vpd.h, under the same names, and in
Intel's FSP Binary Configuration Tool for Bay Trail. This list of properties is
matched up to Intel's E3800 FSPv4 release.
# Boolean properties:
- fsp,enable-sdio
- fsp,enable-sdcard
- fsp,enable-hsuart0
- fsp,enable-hsuart1

- fsp,enable-igd
- fsp,enable-memory-down
If you set "fsp,enable-memory-down" you are strongly encouraged to provide an
"fsp,memory-down-params{};" to specify how your memory is configured. If you do
not set "fsp,enable-memory-down", then the DIMM SPD information will be
discovered by the FSP and used to setup main memory.
