The MMC/SD controllers on am65x and j721e don't in fact detect the write
protect line as inverted. No issues were detected because of this
because the sdwp line is not connected on any of the evms. Fix this by
removing the flag.

The tuning data is leftover in the buffer after tuning. This can cause
issues in future data commands, especially with CQHCI. Reset the command
and data lines after tuning to continue from a clean state.

Command Queuing was enabled completely for J721e controllers which lead
to partial enablement even for Am65x. Complete CQ implementation for
AM65x by adding the irq callback.
