[U-Boot] [PATCH v2 0/6] efi_loader: add HII database protocol

[AKASHI Takahiro]

HII database protocol is the last missing (major?) piece of code so that
we can run unmodified EDKII's shell and UEFI SCT on EFI-enabled u-boot.

The original code was initially written by Leif and Rob a year ago[1],
and now I'm reworking it. The implementation has not been much
enhanced from the original, but I tried to give it clearer implementation
to be able to add more functionality easily later on.
I also addressed the comments by Alex[2] and added a self test on
request of Heinrich.

HII configuration routing protocol and access protocol have only
a skeleton and should be implemented when we need to have *drivers*
that require configuration mechanism.

# Please note that a bunch of warnings are generated by checkpatch.pl,
# but there are also good reasons for not fixing them.

Concerns (if any):
* missing features (see the commit log of patch#2)
* unaligned access to *packed* structure in a package list should be
  cared?

Changes in v2 (Nov 16, 2018)
* add some descriptions to newly added functions
* rename EFI_HII_PACKAGE_[TYPE|LEN]_* to __EFI_HII_PACKAGE_[TYPE|LEN]_*
  as they are of internal use only
* cast a return value (of efi_status_t) to "unsigned int" for printing
