[PATCH v2 0/6] Miscellaneous FWU fixes

[Sughosh Ganu]

The following set of patches are miscellaneous fixes and some
hardening of the FWU update logic.


Changes since V1:
* Squash patch 1 and 2 in the earlier version into a single patch.
* Have a single check for image descriptor offset, and have a log
  message mention that image descriptor mandatory.
* Use a macro FWU_IMG_DESC_OFFSET for the image descriptor offset.
* Use the enum names for primary and secondary partitions from fwu.h
  instead of defining new macros.

  fwu: v2: try reading both copies of metadata
  fwu: v1: do a version check for the metadata
  fwu: check all images for transitioning out of Trial State
  fwu: add dependency checks for selecting FWU metadata version
  fwu: do not allow capsule processing on exceeding Trial Counter
    threshold
  fwu: print a message if empty capsule checks fail
