target/openrisc: Fix writes to interrupt mask register
The interrupt controller mask register (PICMR) allows writing any value
to any of the 32 interrupt mask bits. Writing a 0 masks the interrupt
writing a 1 unmasks (enables) the the interrupt.
For some reason the old code was or'ing the write values to the PICMR
meaning it was not possible to ever mask a interrupt once it was
enabled.
I have tested this by running linux 4.18 and my regular checks, I don't
see any issues.
