PCI: mobiveil: Initialize Primary/Secondary/Subordinate bus numbers

[ Upstream commit 6f3ab451aa5c2cbff33197d82fe8489cbd55ad91 ]

The reset value of Primary, Secondary and Subordinate bus numbers is
zero which is a broken setup.

Program a sensible default value for Primary/Secondary/Subordinate
bus numbers.
