mips: cm: reprime error cause
Accordingly to the documentation ---cut--- The GCR_ERROR_CAUSE.ERR_TYPE field and the GCR_ERROR_MULT.ERR_TYPE fields can be cleared by either a reset or by writing the current value of GCR_ERROR_CAUSE.ERR_TYPE to the GCR_ERROR_CAUSE.ERR_TYPE register. ---cut--- Do exactly this. Original value of cm_error may be safely written back; it clears error cause and keeps other bits untouched.
