Subject: [PATCH 1/2] ATHEROS-ATL1E: Convert iounmap to pci_iounmap

Use pci_iounmap instead of iounmap when the virtual mapping was done
with pci_iomap. A simplified version of the semantic patch that finds this
issue is as follows: (http://coccinelle.lip6.fr/)
    
// <smpl>
@r@
expression addr;
@@
addr = pci_iomap(...)

@rr@
expression r.addr;
@@
* iounmap(addr)
// </smpl>
