[DistroKit] [PATCH v3] tf-a: new package for ARM trusted firmware A

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Trusted Firmware-A (TF-A) is a reference implementation of secure world
software for Arm A-Profile architectures (Armv8-A and Armv7-A).

v2 -> v3:
  - sorted version and md5 Kconfig options to top (mol)
  - Added trailing spaces to align arrow after main prompt (mol)
  - Changed TF_A_VERSION help text to indicate that the version can be any
    git commitsh
  - Removed default value for TF_A_ARTIFACTS (mol)
  - integrated TF_A_VERSION into BUILD_STRING of resulting artifacts
    (Guillermo, mtr)
  - unconditional error if TF_A_ARTIFACTS is empty instead of warning later on
    (mol)
  - removed diplicate Prepare header (mol)
  - resorted make variable definitions
  - avoid unportable install --target-directory (Guillermo)
  - documented support for globbing in TF_A_ARTIFACTS
  - don't glob delete in IMAGEDIR, instead expand the glob in the build
    directory first
v1 -> v2:
  - Made TF_A_ARCH_MAJOR configurable to support 32 bit ARMv8 (Guillermo)
  - Replaces stm32mp-specific TF_A_DTB with TF_A_EXTRA_ARGS to contain
    all board/vendor specific options
  - removed reference to no longer existing CREDITS file
  - removed TF_A_MAKE_OPT contents that are set elsewhere
  - reduced uses of += in favor of directly appending to the string
  - delete old build directory in prepare instead of compile
  - use default compile stage (Guillermo)
  - install artifacts to sysroot /usr/lib/firmware in install stage
  - install artifacts to IMAGEDIR in targetinstall
  - fix clean stage to delete proper artifacts
