The patch
"ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000"
(sha1: 6ff0966052c46efb53980b8a1add2e7b49c9f560)
has moved also start of VMALLOC area because size didn't change.
That's why origin location of vmalloc was
vmalloc : 0xf0000000 - 0xff000000 ( 240 MB)
and now is
vmalloc : 0xf0800000 - 0xff800000 ( 240 MB)
That's why uart virtual addresses need to be changed to reflect this new
memory setup. Starting address should be vmalloc start address.

earlyprintk messages are not appearing on the terminal
emulator during a big endian kernel boot. In BE mode
sending full words to UART will result in unprintable
characters as they are byte swapped versions of printable
ones. So send only bytes.

Enable ARCH_SUPPORTS_BIG_ENDIAN in Kconfig.
zynq_secondary_trampoline is the first function
that is called on secondary CPU.

Virtual address have to have the same offset within
a 2MB aligned section of virtual/phycial address space.
Fix uart0 virtual address to be align with physical one.
Also remove UART_SIZE which is completely unused.

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

Convert low-level debugging routines to make use of debug_ll_io_init().
This is part of the preparation for ARCH_MULTIPLATFORM support for Zynq.
