[GIT PULL] i2c updates for 2.6.36

[Jean Delvare]

Hi Linus,

Please pull a first round of i2c subsystem updates for Linux 2.6.36
from:

git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging.git i2c-for-linus

The big thing here is the multiplexing support, with core support as
well as support for the popular NXP PCA954x family of multiplexers and
switches. It may have a few rough edges left, but overall should work.
The rest are small cleanups.
