Add a cut-down version of the DTS file for the community board
MACCHIATOBin from SolidRun based on Marvell Armada 8040 SoC to suit
the current mainlined Armada 8040 state.
This brings support for mainly SATA, SPI flash and UART. The USB
descriptions are included but are not tested in this form due to the
lack of mainline GPIO.

This is derived from a version from Marvell, but severly cut down,
cleaned up, re-organised and added to to suit mainline kernels. The
only common parts are the header comment, top level model and compatible
strings, the rest has been changed by me in some way.
I'm planning to submit further patches as the mainline Armada 8k support
moves forward.
This is submitted with Rabeeh's confirmation and ack that he (as Solid
Run's CTO) is happy for this to be upstreamed.
Note - the license text is rather "interesting" but matches that which
is already on other ARM64 Marvell-based platforms. I suspect someone at
Free Electrons needs to talk to Marvell to correct the "library" thing,
and clear up the "GPLv2" vs "GPLv2+" confusion in there.
