[PATCH V3 5/5] ARM: tegra: move debug-macro.S to include/debug

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Move Tegra's debug-macro.S over to the common debug macro directory.

Move Tegra's debug UART selection menu into ARM's Kconfig.debug, so that
all related options are selected in the same place.

Tegra's uncompress.h is left in mach-tegra/include/mach; it will be
removed whenever Tegra is converted to multi-platform.

Signed-off-by: Stephen Warren <swarren at nvidia.com>
---
v3: No change; just rebased on updated earlier patches.
v2: Remove redundant default selection in Kconfig.debug, fix indentation
    there.
