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:

+/** @file
+ EFI SMM Control2 Protocol as defined in the PI 1.2 specification.
+
+ This protocol is used initiate synchronous SMI activations. This protocol could be published by a
+ processor driver to abstract the SMI IPI or a driver which abstracts the ASIC that is supporting the
+ APM port. Because of the possibility of performing SMI IPI transactions, the ability to generate this
+ event from a platform chipset agent is an optional capability for both IA-32 and x64-based systems.
+
+ The EFI_SMM_CONTROL2_PROTOCOL is produced by a runtime driver. It provides an
+ abstraction of the platform hardware that generates an SMI. There are often I/O ports that, when
+ accessed, will generate the SMI. Also, the hardware optionally supports the periodic generation of
+ these signals.
