Add proper support for Compulab CM-A510/SBC-A510

This patch set improves current mainline support for the Compulab
CM-A510 System-on-Module (SoM) and its default Compulab SBC-A510
base board. Thanks to Gabriel Dobato who agreed to remote debug and
test the provided DT changes.

On the way to proper support, we
- Rework i2c-mux-pinctrl to honor disabled sub-bus nodes
- Add missing "compulab" vendor prefix
- Fix broken uart[23] reg properties
- Beautify Dove's dtsi files by adding gpio/irq includes, node
  labels for pcie, and some additional pinctrl settings
- Add a node for the internal i2c mux mechanism on Dove SoCs

And finally add a DT include for the Compulab CM-A510 SoM and a DT
board file for the SBC-A510 base board.

Patches are based on stable v3.19 and are indended for the next
merge window (either v3.21 or v4.1). Compulab related changes have
been tested by Gabriel Dobato, I tested on SolidRun CuBox that it
does not break existing Dove boards.

For the i2c-mux-pinctrl, a Tested-by from any user of Tegra20
Seaboard, Tamonten, or Ventana would be nice to see if it is fully
compatible.

I have added MVEBU maintainers to all patches, Wolfram for i2c and
Stephen as the i2c-mux-pinctrl author i2c-mux-pinctrl related patches,
and corresponding lists. As there is no important DT work in here,
I decided to not explicitly add each of the DT maintainers except for
the vendor prefix patch.
