3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mark Brown <[email protected]>

commit db966f8abb9ba74f7d5a7230f51572f52c31c4e5 upstream.

We can enable VMID independently of the bias in some use cases so we need
to ensure that the core device is powered up.
