MIPS: BMIPS: Also call bmips_cpu_setup() for secondary cores
[ Upstream commit e14f633b66902615cf7faa5d032b45ab8b6fb158 ]
The initialization done by bmips_cpu_setup() typically affects both
threads of a given core, on 7435 which supports 2 cores and 2 threads,
logical CPU number 2 and 3 would not run this initialization.
