[PATCH] drm/ttm: declare 'struct device' in ttm_page_alloc.h

[Alexandre Courbot]

Declare 'struct device' explicitly in ttm_page_alloc.h as this file
does not include any file declaring it. This removes the following
warning:

	warning: 'struct device' declared inside parameter list

This warning was visible when compiling Nouveau on -next today.
