Without I2C, we get a link failure:

drivers/ptp/ptp_clockmatrix.o: In function `idtcm_xfer.isra.3':
ptp_clockmatrix.c:(.text+0xcc): undefined reference to `i2c_transfer'
drivers/ptp/ptp_clockmatrix.o: In function `idtcm_driver_init':
ptp_clockmatrix.c:(.init.text+0x14): undefined reference to `i2c_register_driver'
drivers/ptp/ptp_clockmatrix.o: In function `idtcm_driver_exit':
ptp_clockmatrix.c:(.exit.text+0x10): undefined reference to `i2c_del_driver'

Fixes: 3a6ba7dc7799 ("ptp: Add a ptp clock driver for IDT ClockMatrix.")

Sorry, that was flagged by "kbuild test robot" Nov 25.

I was in the process of creating a patch series with other updates,
but you beat me to the punch.  Thank-you.
