The following series adds support for the uefi capsule update feature
on the qemu arm64 platform, along with adding support for the capsule
authentication feature.

The capsule update feature is supported on a platform configuration
booting in a non-secure mode, i.e with -machine virt,secure=off option
set. This results in the platform booting u-boot directly without
the presence of trusted firmware(tf-a). Steps that need to be followed
for using this feature have been provided as part of the documentation.

Support has also been added for enabling the capsule authentication
feature. Capsule authentication, as defined by the uefi
specification is very much on similar lines to the logic used for
variable authentication. As a result, most of the signature
verification code already in use for variable authentication has been
used for capsule authentication.

Storage of the public key certificate, needed for the signature
verification process is in form of the efi signature list(esl)
structure.  This public key is stored on the platform's device tree
blob. The public key esl file can be embedded into the dtb using the
mkeficapsule utility that has been added as part of the capsule update
support series[1]. Steps needed for enabling capsule authentication
have been provided as part of the documentation.

This patch series needs to be applied on top of the capsule update
support patch series from Takahiro Akashi[1]
