H A Denv.c8e2fe0ec Mon Mar 15 02:49:59 CDT 2021 Qing Zhang <zhangqing@loongson.cn> MIPS: Loongson64: Distinguish firmware dependencies DTB/LEFI

Add DTB boot support, only support Loongson-2K1000 processor
for now, determine whether to use the built-in DTB or the DTB
from the firmware by checking the range of CKSEG0 and XKPHYS.
loongson_fw_interface will be used in the future.
