[Intel-gfx] [PATCH] drm/i915: probe lmem before the stolen portion

[Matthew Auld]

At the very least, we have some tests that force the BAR size for
testing purposes, which would result in different BAR size with
stolen-lmem vs normal lmem, since the BAR is only resized as part of the
normal lmem probing.
