Hi Jiawen, Sanket and Basavaraj

I hope you could give a quick test to this patchset to see it won't cause
regression on your HW. This is mostly the same than the first version what
Jiawen tested earlier but in this 3rd version I decided to drop semphore
touching code patches from v2 due they being out of scope and fix a few
things noted by Andy.

Changes are in the patch 3/6 with two minor fixes to comments while moving
them and the patch 6/6 where i2c_dw_wait_transfer() is slightly modified
by Andy's suggestion plus I decided to remove one comment which became
unclear after this patch.

v2:

v1:
