[PATCH 0/3] I2C: assign bus numbers from device tree

Like done with SPI controllers already let's assign the I2C bus numbers
from device tree as well. This avoids confusing bus numbers when the
probe order doesn't match the intended bus number ordering or when
other I2C busses with dynamically assigned numbers are probed in
between.

      i2c: set adapter.nr explicitly to -1
      i2c: get adapter.nr from device tree
      i2c: start dynamic I2C bus numbers at 32
