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.
