eal/linux: disable iopl operation for IBM Power
eal/linux: disable iopl operation for IBM Power

iopl() call is mostly for the i386 architecture. In Power and other
architecture, it doesn't exist. This patch modified rte_eal_iopl_init()
and make it return -1 for Power and other architecture. Thus
rte_config.flags will not contain EAL_FLG_HIGH_IOPL flag for other
architecture.
