hw/npu2-hw-procedures.c: Add nvram option to override zcal calculations
In some rare cases the zcal state machine may fail and flag an error. According
to hardware designers it is sometimes ok to ignore this failure and use nominal
values for the calculations. In this case we add a nvram variable
(nv_zcal_override) which will cause skiboot to ignore the failure and use the
nominal value specified in nvram.
