i2c: Separate Kconfig option for i2c-smbus



Having a separate Kconfig option for i2c-smbus makes it possible to
build that support as a module even when i2c-core itself is built-in.
Bus drivers which implement SMBus alert should select this option, so
in most cases this option is hidden and the user doesn't have to care
about it.

		Say Y here if you want support for SMBus extensions to the I2C
		specification. At the moment, the only supported extension is
		the SMBus alert protocol.

		This support is also available as a module. If so, the module
		will be called i2c-smbus.
