drop "etc/boot-cpus" fw_cfg file and reuse legacy QEMU_CFG_NB_CPUS

since QEMU_CFG_NB_CPUS not going away anytime soon
and serves the same purpose as just added "etc/boot-cpus" fw_cfg
drop support for "etc/boot-cpus" while this code is not
in use yet (i.e. QEMU with "etc/boot-cpus" hasn't been released)
and reuse QEMU_CFG_NB_CPUS instead of it.
