U-Boot SPL for the Xilinx ZynqMP SoCs needs ATF in this format to load
it.

Some platforms (e.g Allwinner ARM64) don't build a FIP image out of
ATF, but only a BL31 image, which is then encapsulated in U-Boot. This
commit adds an ATF option to build such an image.

ATF can be used in different ways:
- ATF encapsulates U-Boot as the BL33, which is what is done on ARM
Juno (currently supported in Buildroot) and Marvell platforms (soon
to be supported)
- U-Boot encapsulates ATF's BL31, which is what is done on Allwinner
ARM64 platforms.
Until now we were assumming the former was always the case, but
obviously it isn't. Therefore, this patch adds an option that allows
to explicitly tell ATF that it encapsulates U-Boot as its BL33.
We adapt the only defconfig that uses ATF so that it enables this
option as appropriate.

Currently, our arm-trusted-firmware unconditionally builds a FIP
(Firmware Image Package). While this is often needed on platforms
where ATF encapsulates U-Boot, it is not the case on some other
platforms where it's U-Boot that encapsulates parts of ATF.
In order to prepare the support for the later platforms, we make
building the FIP image optional, and update the only defconfig we have
that uses ARM Trusted Firmware.
Note: we considered adding a "default y" here to preserve backward
compatibility, but there really isn't any default that is sane:
whether a FIP image needs to be built or not is purely platform
specific.

The license file got reformatted as reStructuredText, but the license itself
didn't change.

[Thomas:
- Rename the package from atfirmware to arm-trusted-firmware, in order
to match upstream.
- Remove option to apply custom patches. We no longer add such options,
and use the global patch directory instead.
- Rename the repo URL/version options, in order to not be Git specific,
in case support for fetching from other VCS is added later. This is
consistent with how other bootloaders handle this.
- Add license information.
- Do not add a weird dependency on the vexpress-firmware package in
Config.in. Instead, simply use it if it's available. Of course, some
configurations (such as the juno configuration) will fail to build if
vexpress-image is not enabled, but it's the responsibility of the
user to create a config that builds.
- Simplify misc aspects in the .mk file.]
