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
