v6->v7: Bjorn's rework and additions of other minor cleanups
v5->v6: rework the patch 1/2, remove the unnecessary check, pointed out by Bjorn.
remove the patch 1/2 cc stable tag, because it's not a serious bug.
v4->v5: Fix some spelling problems and move mpss = 128 << dev->pcie_mpss above to reuse
it, also remove the else braces for code style. thanks for Jon's review and comments.
v3->v4: Call pcie_bus_update_set() only when pcie_bus_config == PCIE_BUS_TUNE_OFF
suggested by Jon Mason, try to change parent mps when parent device is
root port and only one slot connected to it when parent mps > child device
mpss. Other add a patch to fix a issue in pcie_find_smpss() during use
"pci=pcie_bus_safe".
v2->v3: Update CC stable tag suggested by Li Zefan.
v1->v2: Update patch log, remove Joe's reported-by, because his problem
was mainly caused by BIOS incorrect setting. But this patch mainly
to fix the bug caused by device hot add. Conservatively, this
version only update the mps problem when hot add. When the device
mps < parent mps found, this patch try to update device mps.
It seems unlikely device mps > parent mps after hot add device.
So we don't care that situation.
