This series is the fourth version of Mediatek SoCs I2C controller common
bus driver.
Change in v4:
Modify to support i2c_adapter_quirks base on Wolfram's patch [1].
Remove check transfer size and WRRD combine code. Instead, fill quirk
property and let i2c_check_for_quirks to do the filter.

When occur i2c ack error, mtk_i2c_irq is called twice,
first is the ack error interrupt, then the complete interrupt.
i2c interrupt handler should keep the two interrupt value, and only
call complete() for the complete interrupt.

This series provide two patches to optimize mediatek i2c driver.
The first patch will reset dma hardware in init function to make sure
hardware work in good state. The second patch fix i2c interrupt handling
for ACK error. All these patches base on v4.2-rc1.
