Mark Cave-Ayland b342e56b23 target/m68k: use M68K_FEATURE_MOVEFROMSR_PRIV feature for move_from_sr privilege check 
Now that M68K_FEATURE_M68000 has been renamed to M68K_FEATURE_M68K it is easier
to see that the privilege exception check is wrong: it is currently only generated
for ColdFire CPUs when in fact it should also be generated for Motorola CPUs from
the 68010 onwards.

Introduce a new M68K_FEATURE_MOVEFROMSR_PRIV feature which is set for all non-
Motorola CPUs, and for all Motorola CPUs from the 68010 onwards and use it to
determine whether a privilege exception should be generated for the MOVE-from-SR
instruction.
