dm: key: make kernel dtb key has higher priority than U-Boot keys

We add recovery key node with property "u-boot,dm-pre-reloc"
in uboot dts in order to make sure recovery key works normally
even when kernel dtb is load failed. But There are too many
boards for a platform(eg. RK3399/RK3399PRO), which may cause
a mistake key match between boards via U-Boot dts key nodes,
so that we make kernel dtb key has higher priority.
