linux-core Makefile: add GIT_REVISION
This tries to automatically fetch a git revision string and if succeeds, it #defines GIT_REVISION string macro. Packagers can override it by 'make GIT_REVISION=foo'. Update Nouveau to use GIT_REVISION, if defined, instead of DRIVER_DATE in struct drm_driver. Signed-off-by: Pekka Paalanen <pq@iki.fi>
