MIPS: dts: Avoid unneeded built-in.a in DTS dirs

arch/mips/boot/dts/Makefile collects objects from sub-directories into
built-in.a only when CONFIG_BUILTIN_DTB is enabled. Reflect it also to
the sub-directory Makefiles. This suppresses unneeded built-in.a
creation in arch/mips/boot/dts/*/ directories.

While I am here, I replaced $(patsubst %.dtb, %.dtb.o, $(dtb-y)) with
$(addsuffix .o, $(dtb-y)) to simplify the code a little bit.
