ARM: tegra: Sort includes alphabetically

If these aren't sorted alphabetically, then the logical choice is to
append new ones, however that creates a lot of potential for conflicts
because every change will then add new includes in the same location.

ARM: tegra: don't include iomap.h from debug-macro.S

In order to move Tegra's debug-macro.S to a common location for single
zImage, it must not rely on any machine-specific header files such as
<mach/iomap.h>. Duplicate the few physical address definitions that
debug-macro.S relies upon directly into the file.

To avoid tegra_io_desc[] requiring shared knowledge of the UART
mapping's virtual address, use a virtual address outside the ranges
in tegra_io_desc[]. Call debug_ll_io_init() to propagate the mapping
beyond the early pages tables.

ARM: tegra: move iomap.h to mach-tegra

Nothing outside mach-tegra uses this file, so there's no need for it to
be in <mach/>.

Since uncompress.h and debug-macro.S remain in include/mach, they need
to include "../../iomap.h" becaue of this change. uncompress.h will soon
be deleted in later multi-platform/single-zImage patches. debug-macro.S
will need to continue to include this header using an explicit relative
path, to avoid duplicating the physical->virtual address mapping that
iomap.h dictates.

ARM: tegra: annotate IO_*_VIRT pointers

Provide __iomem annotation for IO_*_VIRT pointers, which will propagate
up through IO_TO_VIRT(). Also fixes a 0 to NULL conversion of the base
case to silence sparse.

Unfortunately map_desc takes an unsigned long for the pointer instead of
a void __iomem *. For now, cast explicitly for those cases.

v2: change define to use IOMEM() like many other mach platforms per
comment from Russell.
