[PATCH] make i2c use initcalls everywhere

The use of explicit initializers all over the i2c core anoyed for
long, but the lm_sensors merge with two new files just for initializers
was too much.  Conver all of i2c to sane initialization (mostly
initcall, but some driver also got other cleanups in that area)

Many modern mainboards have some kind of I2C interface integrated. This
is often in the form of a SMBus, or System Management Bus, which is
basically the same as I2C but which uses only a subset of the I2C
protocol.
