gonzo 5cc1585a45 [ig4] Fix I/O timeout issue with Designware I2C controller on AMD platforms 
Due to hardware limitation AMD I2C controller can't trigger pending
interrupt if interrupt status has been changed after clearing
interrupt status bits.  So, I2C will lose the interrupt and IO will be
timed out. Implements a workaround to disable I2C controller interrupt
and re-enable I2C interrupt before existing interrupt handler.
