arm: mvebu: fix vendor prefix typo in kirkwood-synology.dtsi

As reported by Andrew, the vendor prefix for Seiko Instruments, Inc.
S-35390A I2C RTC chip in kirkwood-synology.dtsi has a typo (ssi
instead of sii). This patches fixes it.

Note: i2c devices ignore the optional vendor prefix, which explains
why it worked with the typo and also why there is no backward
compatibility issues with the fix.

arm: mvebu: add uartX labels for Armada SoC serial nodes

This patch adds uartX labels for Armada SoC serial nodes. This is
a preliminary work to be able to easily reference the serial lines
in Device Tree files. One expected use is when providing stdout-path
property for barebox.

arm: mvebu: use recently introduced uart label for stdout-path

Now that labels for uartX are available in Marvell Armada .dtsi files,
this patch replaces the "/soc/internal-regs/serial@12000" found in
armada-xp-lenovo-ix4-300d.dts file for stdout-path property by the more
concise &uart0.

arm: mvebu: move Armada 370/XP pinctrl node definition armada-370-xp.dtsi

What was done by Sebastian in 264a05e19bf5 ("ARM: mvebu: armada-xp:
Add node alias to pinctrl and add base address") and 01c434225ee6
("ARM: mvebu: armada-xp: Use pinctrl node alias") can also be done for
Armada 370, i.e.

 - Rename Armada 370 pinctrl node to pin-ctrl with its address encoded
 - Add a node alias to access the pinctrl node easily.
 - use the newly available alias in existing Armada 370 .dts files

We can even go a bit further by putting the pinctrl node definition in
armada-370-xp.dtsi, with only its reg property defined. This allows us
to then also use the newly defined node alias in armada-xp.dtsi,
armada-370.dtsi.

arm: mvebu: define and use common Armada 370 SPI pinctrl settings

This patch defines common Armada 370 pinctrl settings for spi0 and spi1
interfaces:

 spi0: MPP33-36 as default, MPP32,63-65 as available alternate config
 spi1: MPP49-52 as default

Currently, the Armada 370 DB .dts file has no explicit pinctrl info
for the spi0 interface used to access the flash on the board. The
patch fixes that by also adding explicit pinctrl info (MPP32,63-65)
for this SPI interface.

Note: this patch has the potential to break out-of-tree users w/o
specific pinctrl settings for their spi interfaces if the default
above does not match their config.

arm: mvebu: add .dts file for Synology DS213j

Synology DS213j is a 2-bay NAS powered by a Marvell Armada 370
(88F6710 @1.2Ghz). It is very similar on many aspects to previous
2-bay synology models based on Marvell kirkwood SoC. Here is a
short summary of the device:

 - 512MB RAM
 - boot on SPI flash (64Mbit Micron N25Q064)
 - 1 GbE interface (Armada MAC connected to a Marvell 88E1512
   PHY via SGMII)
 - 2 rear USB 2.0 ports (directly handled by the Armada 370)
 - 2 internal SATA ports handled by the Armada 370: 2 GPIO for
   presence, 2 for powering them
 - two front amber LED (disk1, disk2) controlled by the SoC
 - Seiko S-35390A I2C RTC chip
 - UART0 providing serial console
 - UART1 used for poweroff (connected to a TI MSP430F2111)
 - Fan handled via 4 GPIO (3 for speed, 1 for alarm)

arm: mvebu: add .dts file for Synology DS414

Synology DS414 is a 4-bay NAS powered by a Marvell Armada XP
(mv78230 dual-core @1.33Ghz). It is very similar on many aspects
to previous 4-bay synology models based on Marvell kirkwood SoC.
Here is a short summary of the device:

 - 1GB RAM
 - Boot on SPI flash (64Mbit Micron N25Q064)
 - 2 GbE interfaces (Armada MAC connected to two Marvell 88E1512
   PHY via RGMII)
 - 1 front USB 2.0 ports (directly handled by the Armada 370)
 - 2 rear USB 3.0 ports (handled by an EtronTech EJ168A XHCI
   controller on the PCIe bus)
 - 4 internal SATA ports handled by a Marvell 88SX7042 SATA-II
   controller on the PCIe bus)
 - Seiko S-35390A I2C RTC chip
 - UART0 providing serial console
 - UART1 used for poweroff (connected to a Microchip PIC16F883)

Additional note: the front LEDs the and the two fans are not directly
connected to the SoC and under its control. The former are presumably
driven by the SATA controller, the latter by the PIC.
