mmc: dw_mmc: make multiple instances of dw_mci_card_workqueue

The variable 'dw_mci_card_workqueue' is a global variable shared between
multiple instances of the dw_mmc host controller. Due to this, data
corruption has been noticed when multiple instances of dw_mmc controllers
are actively reading/writing the media. Fix this by adding a instance
of 'struct workqueue_struct' for each host instance and removing the
global 'dw_mci_card_workqueue' instance.
