[PATCH 2/3] ARM: ixp4xx: avoid warning about ioport_map() macro argument processing

Arnd Bergmann [off-list ref] writes:

We get a harmless compiler warning when building the cs89x0 driver
for ixp4xx:

drivers/net/ethernet/cirrus/cs89x0.c: In function 'cs89x0_ioport_probe':
drivers/net/ethernet/cirrus/cs89x0.c:1602:28: warning: suggest parentheses around '+' in operand of '&' [-Wparentheses]
  io_mem = ioport_map(ioport & ~3, NETCARD_IO_EXTENT);

Simply adding parentheses in the macro avoids the warning
