MIPS: Fix regression on BCM4710 processor detection
BCM4710 uses the BMIPS32 core (like BCM6345), not the MIPS 4Kc core as was previously believed. Signed-off-by: Kevin Cernekee <cernekee@gmail.com> Tested-by: Alexandros C. Couloumbis <alex@ozo.com> Patchwork: https://patchwork.linux-mips.org/patch/1837/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
