MIPS: Netlogic: Use PRID_IMP_MASK macro
Use PRID_IMP_MASK macro instead of 0xff00 to extract the processor type. Signed-off-by: Jayachandran C <jchandra@broadcom.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/6868/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
