[3/5] HID: lenovo: Rename fn_lock sysfs attr handlers to make them generic

Commit Message

Hans de Goede July 4, 2020, 1:27 p.m. UTC

Except for a single call, there is nothing keyboard-model specific about
the cptkbd fn_lock sysfs attr handlers, rename them dropping the cptkbd
post-/pre-fix, so that they can be re-used for supporting Fn-lock on the
Thinkpad 10 ultrabook kbd.
