Cristian Ciocaltea 10208bda63 i2c: owl: Clear NACK and BUS error bits 
commit f5b3f433641c543ebe5171285a42aa6adcdb2d22 upstream.

When the NACK and BUS error bits are set by the hardware, the driver is
responsible for clearing them by writing "1" into the corresponding
status registers.

Hence perform the necessary operations in owl_i2c_interrupt().
