Subject: [PATCHv6 05/28] PCI: mobiveil: Use WIN_NUM_0 explicitly for CFG outbound window

As the .map_bus() use the WIN_NUM_0 for CFG transactions,
it is appropriate to pass WIN_NUM_0 explicitly when initializing
the CFG outbound window rather than implicitly relying on the
ob_wins_configure counter.
