Fuhai Wang 3a8a503bd2 ampere/i2c: designware: Issue abort if the bus got stuck during a transfer 
When the master tries to send data to the slave that has gone offline, the
transmission gets stuck. Even when a slave returns back online, the bus
doesn't return to the normal.

This patch works around the issue by issueing abort if master activity
bit is set and then waits for a sometime that to go through. After this
the bus seem to get back operational.
