[ARM] msm: clean up iomap and devices - 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.
