Subject: [PATCH] regulator: max77693: Skip register regulator if no platform
 initialization data

The code in max77693_pmic_dt_parse_rdata() does skip setting rdata if
!rmatch[i].init_data. So we may have some empty entries in rdata[].
We need to skip register regulator if no platform initialization data,
otherwise we may resiter regulator with invalid settings ( the empty entries
of rdata[]).
