ARM: dts: Move .dts files to vendor sub-directories

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.

Remove the usage of skeleton.dtsi in the remaining dts files. It was

memory nodes easier.

The main tricky part to removing skeleton.dtsi is we could end up with
no /memory node at all when a bootloader depends on one being present. I
hacked up dtc to check for this condition.

ARM: dts: mmp2: fix TWSI2

Marvell keeps their MMP2 datasheet secret, but there are good clues
that TWSI2 is not on 0xd4025000 on that platform, not does it use
IRQ 58. In fact, the IRQ 58 on MMP2 seems to be a signal processor:

arch/arm/mach-mmp/irqs.h:#define IRQ_MMP2_MSP 58

I'm taking a somewhat educated guess that is probably a copy & paste
error from PXA168 or PXA910 and that the real controller in fact hides
at address 0xd4031000 and uses an interrupt line multiplexed via IRQ 17.

I'm also copying some properties from TWSI1 that were missing or
incorrect.

Tested on a OLPC XO 1.75 machine, where the RTC is on TWSI2.
