m68k: report correct FPU type on ColdFire MMU platforms
Not all ColdFire SoC parts that have an MMU also have an FPU - so set an FPU type (via m68k_fputype) appropriate for the configured platform. With this set correctly /proc/cpuinfo will report FPU "none" on devices that don't have one. And kernel code paths that initialize FPU hardware will now only execute if an FPU is actually present.
