Some I2C bus implementations need to synchronize with external
entities, such as system firmware, which might also be programming the
same I2C bus.
In order to facilitate this add ->xfer_begin() and ->xfer_end() hooks
which are invoked around pcf_xfer().
[JD: Make these hooks optional.]

i2c-algo-pcf: Discard the mdelay data struct member
Just as i2c-algo-bit, i2c-algo-pcf has an unused mdelay struct member,
which we can get rid of to spare some code and memory.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
