hikey: Add UEFI sources for reference
UEFI needs to be built outside Android build system.
Please follow the instructions in README.
The sources correspond to:

+Caution: This file is used for Duet platform only, do not use them in real platform.
+All variable code, variable metadata, and variable data used by Duet platform are on
+disk. They can be changed by user. BIOS is not able to protoect those.
+Duet trusts all meta data from disk. If variable code, variable metadata and variable
+data is modified in inproper way, the behavior is undefined.
