drm/xe/pf: Drop rounddown_pow_of_two fair LMEM limitation
This effectively reverts commit 4c3fe5eae46b ("drm/xe/pf: Limit
fair VF LMEM provisioning") since we don't need it any more after
non-contig VRAM allocations were fixed. This allows larger LMEM
auto-provisioning for VFs, so instead:
[ ] GT0: PF: LMEM available(14096M) fair(1 x 8192M)
[ ] GT0: PF: VF1 provisioned with 8589934592 (8.00 GiB) LMEM
or
[ ] GT0: PF: LMEM available(14096M) fair(2 x 4096M)
[ ] GT0: PF: VF1..VF2 provisioned with 4294967296 (4.00 GiB) LMEM
we may get:
[ ] GT0: PF: LMEM available(14096M) fair(1 x 14096M)
[ ] GT0: PF: VF1 provisioned with 14780727296 (13.8 GiB) LMEM
and
[ ] GT0: PF: LMEM available(14096M) fair(2 x 7048M)
[ ] GT0: PF: VF1..VF2 provisioned with 7390363648 (6.88 GiB) LMEM
Fixes: 1e32ffbc9dc8 ("drm/xe/sriov: support non-contig VRAM provisioning")
