x86/Kconfig: move and modify CONFIG_I8K

In Kconfig, inside the "Processor type and features" menu, there is
the CONFIG_I8K option: "Dell i8k legacy laptop support". This is
very confusing - enabling CONFIG_I8K is not required for the kernel to
support old Dell laptops. This option is specific to the dell-smm-hwmon
driver, which mostly exports some hardware monitoring information and
allows the user to change fan speed.

This option is misplaced, so move CONFIG_I8K to drivers/hwmon/Kconfig,
where it belongs.

Also, modify the dependency order - change
        select SENSORS_DELL_SMM
to
        depends on SENSORS_DELL_SMM
as it is just a configuration option of dell-smm-hwmon. This includes
changing the option type from tristate to bool. It was tristate because
it could select CONFIG_SENSORS_DELL_SMM=m .

When running "make oldconfig" on configurations with
CONFIG_SENSORS_DELL_SMM enabled , this change will result in an
additional question (which could be printed several times during
bisecting). I think that tidying up the configuration is worth it,
though.

Next patch tweaks the description of CONFIG_I8K.
