EmbeddedPkg: import Lan91x Ethernet controller driver

OpenPlatformPkg (https://git.linaro.org/uefi/OpenPlatformPkg.git) holds a
driver for the SMSC LAN91x, used (among other places) in several ARM Ltd.
software system models.

Import it to EDK2 EmbeddedPkg in preparation for migrating those model
platforms to edk2-platforms.

On the way, update the files to pass PatchCheck.py without warnings
(EFI_D_ -> DEBUG_ and purging tab characters).
Also update .inf file to current version (and sort entries within
sections).
And update copyright dates to reflect this.
