[PATCH 1/2] i2c: expand I2C's id.name to 23 characters

[Anton Vorontsov]

It was discussed[1] that we should match on the first (most specific)
entry in the device tree.

The most lengthy I2C compatible entry for the MPC8349E-mITX MCU
devices is "mc9s08qg8-mpc8349emitx" (w/o vendor name). This means
that we have to allow longer IDs to be used in the I2C subsystem.
