mrg 20aa1cad27 port the arm64 cpu topology setup for big.little to arm.
rename arm64 cpu_do_topology() to arm_cpu_do_topology() and
call it from both arm cpu_attach().

replace both aarch64_set_topology() inline code in arm
cpu_attach() with new arm_cpu_do_topology(), which is called
by the arm64 locore as well (possibly not needed, which would
allow it to become static.)

not yet tested on a real big.little armv7 system.  tested
on rockpro64 and pinebook pro.
