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
+ Provides services to decompress a buffer using the UEFI Decompress algorithm.
+
+ The UEFI Decompress Library enables the decompression of objects that
+ were compressed using the UEFI compression scheme. The UEFI Decompress
+ Library is independent of environment and requires the caller to allocate
+ all required memory buffers.

+ Given a compressed source buffer, this function retrieves the size of

+
+ Retrieves the size of the uncompressed buffer and the temporary scratch buffer
+ required to decompress the buffer specified by Source and SourceSize.
+ If the size of the uncompressed buffer or the size of the scratch buffer cannot
+ be determined from the compressed data specified by Source and SourceData,
+ then RETURN_INVALID_PARAMETER is returned. Otherwise, the size of the uncompressed
+ buffer is returned in DestinationSize, the size of the scratch buffer is returned
+ in ScratchSize, and RETURN_SUCCESS is returned.
+ This function does not have scratch buffer available to perform a thorough
+ checking of the validity of the source data. It just retrieves the "Original Size"
+ field from the beginning bytes of the source data and output it as DestinationSize.
+ And ScratchSize is specific to the decompression implementation.
+
+ If Source is NULL, then ASSERT().
+ If DestinationSize is NULL, then ASSERT().

+
+ @param Source The source buffer containing the compressed data.
+ @param SourceSize The size, in bytes, of the source buffer.

+ by Source and SourceSize is decompressed.
+ @param ScratchSize A pointer to the size, in bytes, of the scratch buffer that
+ is required to decompress the compressed buffer specified
+ by Source and SourceSize.
