drm/ttm: Define a single DRM_FILE_PAGE_OFFSET constant

Browse Source 
Most TTM drivers define the constant DRM_FILE_PAGE_OFFSET of the same
value. The only exception is vboxvideo, which is being converted to the
new offset by this patch. Unifying the constants in a single place
simplifies the driver code.
