m68k: make fp register stores consistent for m68k and ColdFire

Browse Source 
There is no reason we can't make the saved fp registers the same for all
m68k types and ColdFire. There is a little wasted space, but the code
consistency and cleanliness is a big win.

sigcontext.h is an exported header, but currently there is no in-mainline
users of the !__uClinux__ and __mcoldfire__ case that this change effects.
Even better this change actually makes this structure consistent with
the out-of-mainline ColdFire/MMU code.
