This option is no longer used on any davinci board but still selected in defconfigs which causes the following warning:

===================== WARNING ====================== This board uses CONFIG_DM_I2C_COMPAT. Please remove (possibly in a subsequent patch in your series) before sending patches to the mailing list. ====================================================

Remove all references to CONFIG_DM_I2C_COMPAT from davinci.

There are no more "real" users of CONFIG_DM_I2C_COMPAT and we'll soon remove it altogether. Stop building it in sandbox mode.

The following warning is emited when building u-boot for da850-lcdk:

===================== WARNING ====================== This board does not use CONFIG_DM_SPI. Please update the board before v2019.04 for no dm conversion and v2019.07 for partially dm converted drivers. Failure to update can lead to driver/board removal See doc/driver-model/MIGRATION.txt for more info. ==================================================== ===================== WARNING ====================== This board does not use CONFIG_DM_SPI_FLASH. Please update the board to use CONFIG_SPI_FLASH before the v2019.07 release. Failure to update by the deadline may result in board removal. See doc/driver-model/MIGRATION.txt for more info. ====================================================

While we could fix it by selecting CONFIG_DM_SPI, there's no need to build it at all as SPI is disabled on da850-lcdk. Remove all unneeded options from the defconfig.
