[PATCH v6 2/8] Loongson: YeeLoong: add platform specific option

[Wu Zhangin <wuzhangjin@gmail.com>]

From: Wu Zhangjin <wuzhangjin@gmail.com>

This patch add a new LEMOTE_YEELOONG2F option, a yeeloong_laptop/
directory for the coming yeeloong specific support, and for the
ec_kb3310b belongs to yeeloong, so, move it to yeeloong_laptop/ too.
