mmc: sdhci_am654: Fix Command Queuing in AM65x

Browse Source 
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.

Fixes: f545702b74 ("mmc: sdhci_am654: Add Support for Command Queuing Engine to J721E")
