drivers/i2c/designware: namespace soc functions 

Rename the following functions to ensure it's clear that the designware
i2c host controller driver is the one that these functions are
associated with:

i2c_get_soc_cfg() -> dw_i2c_get_soc_cfg()
i2c_get_soc_early_base() -> dw_i2c_get_soc_early_base()
i2c_soc_devfn_to_bus() -> dw_i2c_soc_devfn_to_bus()
i2c_soc_bus_to_devfn() -> dw_i2c_soc_bus_to_devfn()

BUG=b:72121803
