boards: ls1028a: Add support of I2C driver model

Browse Source 
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 ls1028a platform
does not support dm.
