ryan_chen 3af9be5f5c i2c: aspeed: Avoid i2c interrupt status clear race condition. 
commit c926c87b8e upstream.

In AST2600 there have a slow peripheral bus between CPU and i2c
controller. Therefore GIC i2c interrupt status clear have delay timing,
when CPU issue write clear i2c controller interrupt status. To avoid
this issue, the driver need have read after write clear at i2c ISR.
