ARM Versatile multi-platform support

From: Rob Herring <[email protected]>

This series converts ARM Versatile platform to multi-platform. I started this some time ago and some pieces were already merged. The primary piece remaining is converting the PCI host to DT which I was waiting for the common PCI DT parsing to get settled. Now that that is in place as well as a few other pieces are in place like multi-platform fixes for CLCD, we can fully convert Versatile to DT and multi-platform.

There's still a few things that need DT support which can be done later:
- MMC card detect and write protect. Should be able to use VExpress support
- Reboot support. Should be able to re-use Realview reboot code.
- flash phys-map support. Binding exists, but specifically Vpp control is needed.
- CLCD support. Not sure where this is at.

This has been tested on QEMU. A previous version was tested on Versatile/AB by Linus Walleij. Linus reported a problem with the display panel detection. Investigation on h/w is needed still as I have not been able to identify the issue by inspection and the display detection seems to work correctly on QEMU.

Linus had also mentioned to me that QEMU users may have some issue with removing non-DT code as the work flow has to change somewhat. Copying Peter Maydell here for comment (and there's rumors he may have actual PB h/w with PCI as well).
