The ARM PL081 DMA controller can be found in the BCM6846
memory map, and it turns out to work.
The block may be used as DMA engine for some of the
peripherals (maybe the EMMC controller found in the same
group of peripherals?) but it can always be used as a
memcpy engine, which is a generic "blitter".
I tested it with the dmatest module, and it copies
lots of data very fast and fires hundreds of thousands
of interrupts so it works just fine.
Add it to the BCM6846 DTSI file.

This adds the MDIO block found in the BCM6846. Use the new
"brcm,bcm6846-mdio" compatible (merged to the networking tree)
for this block.

The BCM6846 has the same simplistic GPIOs as some other
Broadcom SoCs: plain memory-mapped registers with up to
8 blocks of 32 GPIOs each totalling 256 GPIOs.
Users of the SoC can selectively enable the GPIO blocks
actually used with a certain design.

The arm dts directory has grown to 1559 boards which makes it a bit
unwieldy to maintain and use. Past attempts stalled out due to plans to
move .dts files out of the kernel tree. Doing that is no longer planned
(any time soon at least), so let's go ahead and group .dts files by
vendors. This move aligns arm with arm64 .dts file structure.
There's no change to dtbs_install as the flat structure is maintained on
install.
The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
company (e.g. gemini, nspire)
The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.
