Subject: boards: ls2088a: Add support of I2C driver model.
X-Git-Tag: v2025.01-rc5-pxa1908~2819^2~24

boards: ls2088a: 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 ls2088a platform
does not support dm.
