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 v2:
* Removed incorrect I2C0 and I2C1 Reg addresses
Changes since v1:
* Addressed review comment regarding SPDX License Identifier
* Added I2c0 and I2c1 which cater to AMD's APML Interface
