According to the reference manual the shp_2_mcu / mcu_2_shp
scripts must be used for devices connected through the SPBA.

This fixes an issue we saw with DMA transfers from SPI NOR Flashes.
Sometimes the SPI controller RX FIFO was not empty after a DMA
transfer and the driver got stuck in the next PIO transfer when
it read one word more than expected.

Colibri modules need to be powered using the power pins 3V3 and
AVDD_AUDIO. Add fixed regulators which represent this power rails.
Potentially, those power rails could be switched on a carrier
board. A carrier board device tree could add a own regulator with
a GPIO, and reference that regulator in a vin-supply property of
those new module level system regulators.

Drop the fake simple-bus container 'regulators' and put the

Assign Ethernet clock parents explicitly. The Colibri VF61
uses the 50MHz Ethernet clock provided by PLL5.

The Vybrid SoC has two ethernet interfaces (fec0 and fec1) which
use the same clock source (VF610_CLK_ENET). Therefore this parent
configuration affects multiple consumer devices and need to be
specified in the clock provider node.

Downstream packages like Debian flash-kernel use
/proc/device-tree/model
to determine which dtb file to install.

Hence each dts in the Linux kernel should provide a unique model
identifier.

Commit 8536239e ("ARM: dts: Restructure imx6qdl-wandboard.dtsi for new
rev C1 board.")' created new files imx6dl-wandboard-revb1.dts and
imx6q-wandboard-revb1.dts but used the same model identifier as in
imx6dl-wandboard.dts and imx6q-wandboard.dts.

This patch provides unique model identifiers for revision B1 of
the Wandboard Dual and Wandbaord Quad.

The patch leaves imx6dl-wandboard.dts and imx6q-wandboard.dts unchanged
because it is not foreseeable if the same dts will valid for future
board revisions or not. Furthermore we should avoid unnecessary
changes.
