PCI: mobiveil: Use the 1st inbound window for MEM inbound transactions
The inbound and outbound windows have completely separate control
registers sets in the host controller MMIO space. Windows control
register are accessed through an MMIO base address and an offset
that depends on the window index.
Since inbound and outbound windows control registers are completely
separate there is no real need to use different window indexes in the
inbound/outbound windows initialization routines to prevent clashing.
To fix this inconsistency, change the MEM inbound window index to 0,
mirroring the outbound window set-up.
