[PATCH 3/3] i2c: start dynamic I2C bus numbers at 32

[Sascha Hauer <s.hauer@pengutronix.de>]

To avoid clashes with bus numbers derived from device tree let's start
the dynamically assigned bus numbers at 32.

Usually the SoC internal I2C controllers with fixed bus numbers are
registered before any other controllers, but with deep probe support
this is no longer always true. In my case I saw a HDMI internal I2C
controller registered before some SoC controller messing up the
numbering.
