[PATCH v4 2/5] MIPS: Loongson64: lemote-2f move ec_kb3310b.h to include dir and clean up

From: Jiaxun Yang
Date: Sat Dec 09 2017 - 01:50:53 EST

To operate EC from platform driver, this head file need able to be include
from anywhere. This patch just move ec_kb3310b.h to include dir and
clean up ec_kb3310b.h.
