Thomas Bogendoerfer ce6c0a593b MIPS: fw: arc: use call_o32 to call ARC prom from 64bit kernel ...

When using a 64bit kernel with generic spaces setup stack is
also placed in XKPYHS, which the 32bit PROM can't handle.
By using call_o32 for ARC_CALLs a stack placed in KSEG0 is used
when calling PROM.
