Pull DeviceTree updates from Rob Herring:

 - Convert to use memblock_virt_alloc in DT code which supports
   bootmem arches. With this we can remove the arch specific
   early_init_dt_alloc_memory_arch() functions.

 - Enable running the DT unittests on UML

 - Use SPDX license tags on DT files

 - Fix early FDT kconfig ifdef logic

 - Clean-up unittest Makefile

 - Fix function comment for of_irq_parse_raw

 - Add missing documentation for linux,initrd-{start,end} properties

 - Clean-up of binding examples using uppercase hex

 - Add trivial devices W83773G and Infineon TLV493D-A1B6

 - Add missing STM32 SoC bindings

 - Various small binding doc fixes
