Pull more devicetree updates from Rob Herring:
"This is mostly a treewide clean-up from Krzysztof. There's also a
couple of fixes and things that fell thru the cracks.
I must say this has been a nice merge window without bindings dumped
in at the last minute introducing warnings.
Summary:
- Treewide dropping of redundant 'binding' or 'schema' from schema
titles. This will be followed up with a automated check to catch
these.
- Re-sort vendor-prefies
- Convert GPIO based watchdog to schema
- Handle all the variations for clocks, resets, power domains in i.MX
PCIe binding
- Document missing 'power-domains' property in mxsfb
- Fix error with path references in Tegra XUSB example
- Honor CONFIG_CMDLINE* even without /chosen node"
