[PATCH] MIPS: SMTC: fix implicit declaration of set_vi_handler

[Florian Fainelli <florian@openwrt.org>]

This patch fixes the following implicit declaration while building with
MIPS SMTC support enabled:

arch/mips/kernel/smtc.c: In function 'setup_cross_vpe_interrupts':
arch/mips/kernel/smtc.c:1205:2: error: implicit declaration of function
'set_vi_handler' [-Werror=implicit-function-declaration]
cc1: all warnings being treated as errors

Ralf, John,

This is applicable to both mips-for-linux-next and master.
