i2c: xiic: Make bus names unique
This driver is for an FPGA logic core, so there can be arbitrarily many instances of the bus on a given system. Previously all of the I2C bus names were "xiic-i2c" which caused issues with lm_sensors when trying to map human-readable names to sensor inputs because it could not properly distinguish the busses, for example. Append the platform device name to the I2C bus name so it is unique between different instances.
