google/fizz: Disable unused i2c lines
As cr50 has now switched to using SPI, no need to enable the i2c1
anymore. Additionally, disabled unused I2C devices -- I2C0, I2C2 and
I2C3.
BUG=b:69374421
BRANCH=None
TEST=test on fizz celeron. Make sure /dev/tpm0 created on (many)
reboots. cat /proc/interrupts. Make sure # interrupts for 16
after booting is reasonable (not > 10k) and idma64.0,
i2c_designware.0 are not listed with that interrupt line anymore.
Should look something like this:
16: 1174 0 IO-APIC 16-fasteoi i801_smbus, snd_soc_skl, AudioDSP
