If some bits were cleared by i2c_dw_read_clear_intrbits_slave() in i2c_dw_isr_slave() and not handled immediately, those cleared bits would not be shown again by later i2c_dw_read_clear_intrbits_slave(). They therefore were forgotten to be handled. i2c_dw_read_clear_intrbits_slave() should be called once in an ISR and take its returned state for all later handlings.
