efi: capsule: Add support for uefi capsule authentication
Add support for authenticating uefi capsules. Most of the signature
verification functionality is shared with the uefi secure boot
feature.
The root certificate containing the public key used for the signature
verification is stored as part of the device tree blob. The root
certificate is stored as an efi signature list(esl) file -- this file
contains the x509 certificate which is the root certificate.
