net: socionext: include linux/io.h to fix build

BugLink: https://bugs.launchpad.net/bugs/1747792
I ran into a randconfig build failure:

drivers/net/ethernet/socionext/netsec.c: In function 'netsec_probe':
drivers/net/ethernet/socionext/netsec.c:1583:17: error: implicit declaration of function 'devm_ioremap'; did you mean 'ioremap'? [-Werror=implicit-function-declaration]

Including linux/io.h directly fixes this.
