drm/xe/pf: Drop 2GiB limit of fair LMEM allocation

Browse Source 
Since commit 678ccbf987 ("drm/xe/vram: drop 2G block
restriction") we are able to provision VFs with more than 2GiB.
Drop our temporary limit of maximum fair LMEM size that was added
just to avoid hitting -EINVAL from auto-provisioning.
