hwmon: (dell-smm) rewrite CONFIG_I8K description
It is not the laptops, but the /proc/i8k interface that is legacy (or so
I think was the intention of the help text author). The old description
was confusing, fix this.
The phrase "Say Y if you intend to run this kernel on old Dell laptops
or want to use userspace package i8kutils." was introduced in 2015, in
commit 039ae58503f3 ("hwmon: Allow to compile dell-smm-hwmon driver without /proc/i8k")
I think that "old laptops" was about hotkey and Fn key support - this
driver in the 2.4 kernels' era apparently had these capabilities
(see: https://github.com/vitorafsr/i8kutils , description of
"repeat_rate" kernel module parameter).
