Subject: [PATCH next] PCI: brmstb: Fix type mismatch for num_inbound_wins in brcm_pcie_setup()

Change num_inbound_wins from u8 to int in brcm_pcie_setup() function to correctly 
handle potential negative error codes returned by brcm_pcie_get_inbound_wins().
The u8 type was inappropriate for capturing the function's return value,
which can include error codes.
