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.

Checks EXT_CSD_PARTITION_SETTING_COMPLETED bit before
computing enhanced user area offset and size, and
adding mmc general purpose partitions. The two needs
EXT_CSD_PARTITION_SETTING_COMPLETED bit be set to be
valid (as described in JEDEC standard).
Warn user in case of misconfiguration.
Signe
JEDEC standard requires that EXT_CSD_PARTITION_SETTING_COMPLETED bit
must be set in order to take in account enhanced area and general purpose
partitions (gp) values.
Current code doesn't checks this bit and blindly trust enhanced area and
gp values. Moreover, "enhanced_area_en" attribute was set

Almost all case is selected to 0.
(It's not correct sample-clock value.)
Since it set to wrong value, HS200 mode don't work fine.
If we want to select the correct value, it has to check from 1 to 7.(skip 0)
