drivers/i2c/designware: reduce API complication for bus config

Right now dw_i2c_get_soc_cfg() is expecting the SoC to implement
that callback for obtaining the bus config. However, we're currently
forcing another parameter of struct device so one can do the lookup.
This works for Intel-based systems since the struct device was needed
to program the BAR, etc. However, from an API standpoint, it just
complicates matters by needing to obtain the struct device. The SoC
already has knowlege of its own devices so it can get the config
itself by bus number. Therefore, remove that contraint from the API.
