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[]).

It should be legal to have no init data, this should make the regulator available read only (allowing the current settings to be read back but nothing else).
