Allows gdb to access contents of user mode mapped BOs. System memory
is handled by TTM using kmap. Other memory pools require a new driver
callback in ttm_bo_driver.

v2:

* swap in BO if needed
* make driver callback more generic to handle private memory pools
* document callback return value
* WARN_ON -> WARN_ON_ONCE

Masahiro Yamada 2da83319a1 drm/ttm: fix include notation and remove -Iinclude/drm flag 
For the C file, include <drm/*.h> instead of relative path from
include/drm.

For headers in include/drm/ttm, simplify the <tty/*.h> with "*.h".

This allows us to remove the -Iinclude/drm compiler flag from
drivers/gpu/drm/ttm/Makefile (and from other drivers' Makefiles).
