The recently added mlxsw driver produces warnings in ARM
allmodconfig:
drivers/net/ethernet/mellanox/mlxsw/pci.c: In function 'mlxsw_pci_cmd_exec':
drivers/net/ethernet/mellanox/mlxsw/pci.c:1585:59: warning: right shift count
>= width of type [-Wshift-count-overflow]
linux/byteorder/big_endian.h:38:51: note: in definition of macro '__cpu_to_be32'
drivers/net/ethernet/mellanox/mlxsw/pci.c:76:2: note: in expansion of macro
'iowrite32be'
This changes the type of the local variable to u64, which gets rid of the
warning and seems nicer than adding #ifdefs.
