At present if U-Boot proper uses driver model for I2C, then SPL has to also. While this is desirable, it places a significant barrier to moving to driver model in some cases. For example, with a space-constrained SPL it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves adjusting some drivers.
This patch introduces a separate Kconfig symbols for enabling DM_I2C and DM_I2C_GPIO support in SPL.
This will also help to get away from dirty workarounds to achieve non-DM I2C support for SPL, which is currently used in some board header files like:
ifdef CONFIG_SPL_BUILD undef CONFIG_DM_I2C endif
