drm: un-inline drm_legacy_findmap()
Un-inline drm_legacy_findmap() to not depend on struct drm_device
definition within drm_legacy.h, so that a forward declaration suffices.
Also include drm_hashtab.h in drm_legacy.h to make it more
self-contained. Make it easier to drop drmP.h includes.
v2: avoid including drm_device.h by un-inlining (Daniel)
[Updated commit message per Laurent's review while applying.]
