hikey: Add UEFI sources for reference

UEFI needs to be built outside Android build system.
Please follow the instructions in README.

+# Instance of PCD Library using PCD Protocol.

+#

+# There are two PCD protocols as follows:

+#   1) PCD_PROTOCOL

+#      It is EDKII implementation which support Dynamic/DynamicEx Pcds.

+#   2) EFI_PCD_PROTOCOL

+#      It is defined by PI specification 1.2, Vol 3 which only support dynamicEx 

+#      type Pcd.

+#

+# For dynamicEx type PCD, it is compatible between PCD_PROTOCOL and EFI_PCD_PROTOCOL.

+#

+# This library instance uses the PCD_PROTOCOL to handle dynamic PCD request and use

+# EFI_PCD_PROTOCOL to handle dynamicEx type PCD.

+#

+# Note: A driver of type DXE_RUNTIME_DRIVER and DXE_SMM_DRIVER can only use this DxePcdLib 

+#  in their initialization without any issues to access Dynamic and DynamicEx PCD. They can't 

+#  access Dynamic and DynamicEx PCD in the implementation of runtime services and SMI handlers.

+#  Because EFI_PCD_PROTOCOL is DXE protocol that is not aviable in OS runtime phase.
