[PATCH V5 00/12] IOT2050-related enhancements

(Almost) flushing our upstream queue for the IOT2050 device, this mostly
brings board-specific changes such as:

 - updated build process and firmware layout for PG1 vs. PG2 devices
 - more watchdog preparations
 - preparations for verified boot on IOT2050 Advanced devices

This series depends on

("env: Enhancements for establishing variable protection")

Changes in v5:
 - factored out two patches

Changes in v4:
 - rebased over latest master

Changes in v3:
 - further reworked patch 1 to load default env directly, leaving driver
   ordering alone

Changes in v2:
 - rebased over latest master
 - reworked patch 1 to be less invasive to the code
 - added "iot2050: use the named gpio to control the user-button"

Still in our backlog is support for a new variant that comes with M.2
slots. Related DT patches were sent to the kernel and are under review
