[PATCH v2 0/7] efi: Enhance capsule loader to support signed Quark images

[Jan Kiszka <jan.kiszka@siemens.com>]

This addresses the review feedback provided on round 1, specifically
- refactored queue to keep the Quark mess in 
- only check for CSH on Quark CPUs
- added some smaller cleanups of the capsule loader
- documented capsule header / linked to original code

See last patch for the background of the series.

The series has been tested on the Galileo Gen2, to exclude regressions,
with a firmware.cap with AND without security header and the SIMATIC
IOT2040 which requires the header because of its mandatory secure boot.
