Subject: [PATCH] MIPS: migrate to generic rule for built-in DTBs

Commit 654102df2ac2 ("kbuild: add generic support for built-in boot
DTBs") introduced generic support for built-in DTBs.

Select GENERIC_BUILTIN_DTB and BUILTIN_DTB_ALL when the built-in DTB
support is enabled.

DTBs compiled under arch/mips/boot/dts/ will be wrapped by the generic
rule in scripts/Makefile.vmlinux.
