Subject: [PATCH] xtensa: add boot-elf targets to extra-y

The commit 8fe87a92f262 ("kbuild: always create directories of targets")
exposed an issue in the xtensa makefiles that results in the following
build error in a clean directory:
  scripts/Makefile.build:374: arch/xtensa/boot/boot-elf/boot.lds] Error 1
    arch/xtensa/boot/boot-elf/bootstrap.S:21: fatal error:
    opening dependency file arch/xtensa/boot/boot-elf/.bootstrap.o.d:
    No such file or directory

Intermediate targets in arch/xtensa/boot/boot-elf don't get into
'targets' and build directory is not created for them.
Add boot.lds and bootstrap.o to extra-y.
