Merge branch 'next' of https://gitlab.denx.de/u-boot/custodians/u-boot-x86 into next

- Enhance the 'zboot' command to be more like 'bootm' with sub-commands
- The last series of ACPI core changes for programmatic generation of
  ACPI tables
- Add all required ACPI tables for ApolloLake and enable ACPIGEN on
  Chromebook Coral
- A feature minor enhancements to the 'hob' command
- Intel edison: Support for writing an xFSTK image via binman
