[PATCH RESEND] drm/ttm: remove declaration of ttm_tt_cache_flush

[Alexandre Courbot <acourbot@nvidia.com>]

ttm_tt_cache_flush's implementation was removed in 2009 by commit
c9c97b8c, but its declaration has been hiding in ttm_bo_driver.h since
then.

It has been surviving in the dark for too long now ; give it the mercy
blow.
