ptp: clockmatrix: add I2C dependency
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.")
