[PATCH 1/2] mfd: superio: smsc: fix C99ism initial declaration in for loop

[Ahmad Fatoum]

Codebase is meant to be gnu89, but was only enforced starting
with bc4840e98b94 ("kbuild: add -Wmissing-prototypes and -std=gnu89
to KBUILD_HOSTCFLAGS"). Since then, this driver no longer compiles.
Fix this.
