Initial introduction of AMD EthanolX platform equipped with an
Aspeed ast2500 BMC manufactured by AMD.
AMD EthanolX platform is an AMD customer reference board with an
Aspeed ast2500 BMC manufactured by AMD.
This adds AMD EthanolX device tree file including the flash layout
used by EthanolX BMC machines.
This also adds an entry of AMD EthanolX device tree file in Makefile.

Changes since v1:
* Addressed review comment regarding SPDX License Identifier
* Added I2c0 and I2c1 which cater to AMD's APML Interface

This is unusual. i2c1 is at 0x80; this will clash with i2c2.
Note that the i2c naming in linux counts from zero, whereas the ASPEED
docs count from 1. So if your board layout has I2C1, you actually want
i2c2 in the device tree.
