When PCIe PHY link never came up and vpcie regulator is present, there

Add a new host_exit() callback for i.MX PCIe driver to disable this

This looks like a good improvement, though it still looks like there are
issues given the checks for the regulator being NULL.  This might be
better fixed as a separate patch though.
