In .config I do not see any DM_I2C string. Should I something enable?
What is needed for OMAP I2C? In .config is:

CONFIG_SYS_I2C_OMAP24XX=y
CONFIG_SYS_OMAP24_I2C_SLAVE=1
CONFIG_SYS_OMAP24_I2C_SPEED=100000
CONFIG_SYS_I2C_BUS_MAX=3

But strange is that there is no problem in qemu emulator without any
crash.
