EmbeddedPkg/FdtPlatformDxe: Add 'setfdt' EFI Shell command
The 'setfdt' EFI Shell command allows to define a new FDT as the prefered one for development purposes. It allows to trigger the run of the FDT installation process as well. Please refer to the README.txt file for more comprehensive description.
