arm64: dts: mediatek: mt6797: Remove bogus id property in i2c nodes

All of the I2C nodes in this devicetree has a bogus "id" property,
which was probably specifying the I2C bus number.

This property was never parsed and never used - and besides, it
also gives dtbs_check warnings: remove it from all i2c nodes.
