drivers: i2c: clean up Kconfig file
Several minor changes to clean up I2C Kconfig file - align help text - remove duplicate dependencies - use unified naming for I2C port options - replace outdated references to datasheet in help text - add comments at the end of 'endif' Change-Id: I452083feb29f40909e6e38324ff9d9961fc6bd07 Signed-off-by: Piotr Mienkowski <piotr.mienkowski@gmail.com>
