i2c: ocores: set IACK bit after core is enabled
Setting IACK bit when core is disabled does not clear the "Interrupt Flag"
bit in the status register, and the interrupt remains pending.
Sometimes it causes failure for the very first message transfer, that is
usually a device probe.
Hence, set IACK bit after core is enabled to clear pending interrupt.
