Currently Intel Baytrail I2C semaphore is a feature of the DW APB I2C
platform driver. It's a bit confusing to see it's config in the menu at
some separated place with no reference to the platform code. Lets move the
config definition under the if-I2C_DESIGNWARE_PLATFORM clause. By doing so
the config menu will display the feature right below the DW I2C platform
driver item and will indent it to the right so signifying its belonging.

If you say yes to this option, support will be included for the
Synopsys DesignWare I2C adapter.

Is the added "if I2C_DESIGNWARE_PLATFORM" needed here? Should the
"depends on" be enough?
