boards: lx2160a: Add support of I2C driver model
DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C
API when DM_I2C is used. When DM_I2C_COMPAT is not enabled for
compilation, a compilation error will be generated. This patch solves
the problem that the i2c-related api of the lx2160a platform does not
support dm.
