30091404af i2c-algo-pcf: Add adapter hooks around xfer begin and end
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.]

0573d11b2b i2c-algo-pcf: Multi-master lost-arbitration improvement
Improve lost-arbitration handling of PCF8584.  This is necessary for
support of a currently out-of-kernel driver for Sun Microsystems E250
environmental management; perhaps others.

3269711b76 i2c: Discard the i2c algo del_bus wrappers
They are all only calling i2c_del_adapter, so we may as well do
it directly.

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!
