ARM: zynq: add support for ARCH_MULTIPLATFORM
The majority of changes are necessary to remove dependencies on header
files within arch/arm/mach-zynq/include/mach:
uncompress.h
- Deleted. It is unused for ARCH_MULTIPLATFORM builds.
uart.h:
- Move uart definitions out of uart.h into debug/zynq.S, which is
now the only user
zynq_soc.h:
- Move SCU address definitions into common.c.
- Other #defines, such as PERIPHERAL_CLOCK_RATE, TTC0_BASE, etc, are
unused and can be dropped
