dtx_diff returns an empty diff, nice

Couple further suggestions:
- wdog can probably enabled unconditionally
- same for blsp dma since there's only one host so it must be
used by something
- same for crypto engine as it's a common piece of hw
- you can drop mux{}, pinmux{}, pinconf{} from pin nodes, just add
the properties directly under the pin nodes
- this devicetree could use some schema warnings cleanup (make dtbs_check
plus things like no underscores in node names)
