i2c: hisi: Only handle the interrupt of the driver's transfer

Browse source

The controller may be shared with other port, for example the firmware.
Handle the interrupt from other sources will cause crash since some
data are not initialized. So only handle the interrupt of the driver's
transfer and discard others.
