arm: mvebu: add Synology DS213j and DS414 .dts files

Hi,

This series adds .dts files for Synology DS213j (armada 370 2-bay NAS) and DS414 (armada XP 4-bay NAS) devices. It is based on comments received on a v0 submission of DS213j .dts file [1].

Andrew, in this v1, the two .dts files are still separate w/o any common .dtsi. I took a quick look it seems there are small differences between the two which make me wonder if its worth the trouble:

- DS414 fans are not handled by the SoC
- various pinctrl variations
- a tiny difference in SPI flash partitioning
- phy-mode for ethernet interfaces
- different comments associated w/ same nodes (e.g. uart1)
- etc

Could you take a quick look and tell me if you think it's worth it? I'll follow what you'll decide.

Cheers,

a+

Changes since v0:

- Added a comment at the beginning of DS213j and DS414j .dts file regarding the need for a recent Marvell bootloader. Arnd suggested to do a specific .dtb file for new and old bootloaders but I think if we follow this path for DS414 and DS213j, we will probably have to do it for all Armada-based synology NAS and possibly for other Armada 370/XP based devices. Opting for recent bootloaders config and having a comment is easier. It is likely that a user already has a recent bootloader. Otherwise, upgrade is a one click process anyway. If a user thinks it is easier to have two different .dts files in the kernel, she will still be able to push a patch.
- Added a comment in the .dts file about the bootloader screwing the kernel if the environment is saved.
- Kept GPL licence for .dts file
- Fixed bad naming of node and alias (_ vs -)
- Added micron vendor prefix for n25q064 flash
- Disabled SoC RTC; a Seiko S-35390A is used as main RTC
- Added comments about the purpose of each serial port
- Added stdout-path = &uart0; to help barebox. A specific patch is included in the series to provide labels for uart serial nodes
- Added patch for DS414 .dts file
