[ARM] msm: clean up iomap and devices

Browse Source 
- Add some more peripherals (sdcc, etc) to the iomap.
- Remove virtual base addresses for devices that we should be passing
  physical addresses to drivers via resources and ioremap()ing.
- don't try to use uarts for ll debug once the mmu is enabled due to
  problems with the peripheral window
- make base addresses void __iomem * and fixup irq.c and timer.c
- Remove common.c and bring in devices.c/devices.h similar to
  the PXA architecture.
