Fix interrupt handling for or1k.
- During interrupt handling the PICSR, table pointers and current
interrupt line have been saved in incorrect registers and/or stored on
the stack.
- Save the pointer in r16/r18, PICSR in r20 and the current interrupt
line in r22. Those are callee-saved registers, so that the register
values will be preserved.
* or1k/interruts-asm.S: Change registers to callee-saved.
