The management firmware HSI contains masks which are already
shifted to their right place, so QED_MFW_SET_FIELD() is clearing
incorrect fields by shifting the mask by the offset.

Luckily, today we set the fields in an incrementing order [so we're
not erasing any previously set fields], but this still needs fixing.
