mmc: card: remove HPI and Cache quirks for Hynix cards 



This change removes quirks for Hynix cards.
These quirks were used to avoid HPI and Cache
feature for specific Hynix cards due to
issues such as data corruption.
After further discussion with the card vendor it was
decided to restore the usage of these features.
