Laurent Vivier aa69ab54ad target/m68k: implement fmove.l #<data>,FPCR 
The immediate value mode was ignored and instruction execution
ends to an invalid access mode.

This was found running 'R' that set FPSR to 0 at startup with
a 'fmove.l #0,FPSR' in qemu-system-m68k emulation and triggers a
kernel crash:
