i.MX device tree change for 6.1

- A series from Alexander Stein to add missing properties for i.MX6 SRAM.
- Drop 'interrupts' property when 'interrupts-extended' is present. This
  fixes a dtbs_check warning with i.MX6 DT.
- Update device trees to use generic name 'dma-controller' for SDMA.
- A set of changes from Krzysztof Kozlowski to align SPI, LED and
  gpio-keys node name with dtschema.
- A series of indentation and white-space cleanups from Marcel Ziswiler
  to address various checkpatch warnings.
- Add DDR pinmux defines to VF610 DT header.
- A couple of changes from Peng Fan to update clock-names and add IPG
  clock for i.MX7ULP LPI2C devices.
- Improve device tree structure for Kontron i.MX6UL/ULL based boards.
- A series of changes from Tim Harvey to add CAN regulator for Gateworks
  i.MX6QDL boards.
- Various small and random board specific updates.
