drm/ttm: Fix @alloc_flags description

Stephen Rothwell reports htmldocs warnings when merging drm-misc tree:

Documentation/gpu/drm-mm:40: include/drm/ttm/ttm_device.h:225: ERROR: Unknown target name: "ttm_allocation". [docutils]
Documentation/gpu/drm-mm:43: drivers/gpu/drm/ttm/ttm_device.c:202: ERROR: Unknown target name: "ttm_allocation". [docutils]
Documentation/gpu/drm-mm:73: include/drm/ttm/ttm_pool.h:68: ERROR: Unknown target name: "ttm_allocation_pool". [docutils]
Documentation/gpu/drm-mm:76: drivers/gpu/drm/ttm/ttm_pool.c:1070: ERROR: Unknown target name: "ttm_allocation_pool". [docutils]

Fix these by adding missing wildcard on TTM_ALLOCATION_* and
TTM_ALLOCATION_POOL_* in @alloc_flags description.

Fixes: 0af5b6a8f8dd ("drm/ttm: Replace multiple booleans with flags in pool init")
Fixes: 77e19f8d3297 ("drm/ttm: Replace multiple booleans with flags in device init")
Fixes: 402b3a865090 ("drm/ttm: Add an allocation flag to propagate -ENOSPC on OOM")
