1.8.1.1
From: Jun Gao <[email protected]>
Add i2c compatible for MT7622. Compare to MT8173 i2c controller,
MT7622 limits message numbers to 255, and does not support 4GB
DMA mode.

Hi, Jun
the patch for new soc support and clean-ups should better be in separate
patch following previous Matthias suggestion.
http://lists.infradead.org/pipermail/linux-mediatek/2017-August/009740.html
And also spelling for Mediatek should be corrected using MediaTek.
