dts: msm8953-xiaomi-common: sakura: This device uses xiaomi-daisy dtb for kernel

The two devices are identical, only except a different partition scheme.

Even though we already have defined `lk2nd,dtb-files`,
we still want this because this is for matching dtb in boot.img
rather than matching filename.
