[PATCH v2 0/9] i2c: designware: Generic polling mode code

Hi

This is mostly the same than the first version implementing generic
polling mode code for the i2c-designware except three more patches added
before them.

Andy had an idea we should have more consistency to platform flags naming
and the first three patches are around that. Michael started the
conversion so I took his patch from an internal set and put first. Since
this version touches Intel PUNIT semaphore code I Cc'ed Hans.

Andy and Andi had comments to "Uniform initialization flow for polling
mode" but I decided to not implement a separate helpter function for
interrupt request as it in my opinnion does not make code any easier to
read.

I also wanted to retain single return point in the
i2c_dw_wait_transfer() implemented by the last patch since I had some
debug code there when doing the first version.
