[SRU][Xenial][PATCH] System stalls when creating device node on booting

[Phidias Chiang]

We've found on some Apollo Lake system stalls for around 4 seconds on
function `wait_for_completion` when creating nodes in devtmpfs. With 70+
nodes created it can be stalled for 5+ minutes when booting.

This patch can be clean picked, and shows positive result on multiple
Apollo Lake system. The patch is already in v4.5+ so Yakkety is not
affected.
