Subject[PATCH v4 0002/0003] mmc: Replace "enhanced_area_en" attribute by "partition_setting_completed"
Replace ext_csd "enhanced_area_en" attribute by
"partition_setting_completed". It was used whether or
not enhanced user area is defined and without checks of
EXT_CSD_PARTITION_SETTING_COMPLETED bit.
