arm64: dts: qcom: sm8450-nagara: Disable empty i2c bus

As much as it hurts me, there is no FM radio chips on these devices.
It seems to be present on Japanese models, but these are not available
globally and differ in a few more ways anyway (such as a super high-tech
NFC chip). Since it's the only subdevice of its I2C host bus, disable
said bus to save some power.
