This new file is almost identical to bcm2835-rpi.dts. Perhaps we can use
some include files to share the common portions so they aren't
duplicated. Roughly:
* Move all the common content from bcm2835-rpi.dts into bcm2835-rpi.dtsi.
* Update bcm2835-rpi.dts to include bcm2835-rpi.dtsi to get all the
common parts, and add the few lines of differences.
* Update this patch similarly.
Does that make sense?
A couple changes to this patch and the existing bcm2835-rpi.dts might
reduce the differences even further, leading to more common code in
bcm2835-rpi.dtsi:
- Add the PWR LED to bcm2835-rpi-b.dts, if appropriate.
- Add the I2S pinmux settings for B+ too.

That label doesn't exist; it should be &sdhci. Consequently:

This new DT file should be added to arch/arm/boot/dts/Makefile too.
