pic_width when written into the PPS register is divided by the no.
of vdsc instances first but the actual variable that we compare it
to does not change i.e vdsc_cfg->pic_width hence when reading the
register back for pic_width it needs to be multiplied by
num_vdsc_instances rather than being divided.
