data->{blocks, blocksize, flags} are all used outside of the if clause
checking whether data is not NULL.
Fix this to avoid dereferencing null pointers.

To use the sdhci helpers we have to switch to the sdhci accessors.
Also use sdhci_read_response().

This adds a driver for the SDHCI controller found on Marvell Dove SoCs.
Despite a missing pinctrl driver, corresponding MPP config has to be
set on a per board basis.
This driver was succesfully tested with Solidrun Dove Cubox.
