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.

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

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