When the optee driver is compiled into the kernel while the i2c core is configured as a module, the i2c symbols are not available.
This commit addresses the situation by disabling the i2c support for this use case while allowing it in all other scenarios:
i2c=y, optee=y i2c=m, optee=m i2c=y, optee=m i2c=m, optee=y (not supported)
