i2c-omap: OMAP3430 Silicon Errata 1.153
When an XRDY/XDR is hit, wait for XUDF before writing data to DATA_REG. Otherwise some data bytes can be lost while transferring them from the memory to the I2C interface. Do a Busy-wait for XUDF, before writing data to DATA_REG. While waiting if there is NACK | AL, set the appropriate error flags, ack the pending interrupts and return from the ISR.
