LoongArch: Fix built-in DTB detection
fdt_check_header(__dtb_start) will always success because kernel
provides a dummy dtb, and by coincidence __dtb_start clashed with
entry of this dummy dtb. The consequence is fdt passed from firmware
will never be taken.
Fix by trying to utilise __dtb_start only when CONFIG_BUILTIN_DTB is
enabled.

Fixes: 7b937cc243e5 ("of: Create of_root if no dtb provided by firmware")
