HID: force HID depending on INPUT

In most configurations, INPUT is actually a boolean: either y or disabled,
but when it's disabled, you can't do much on your average laptop.

But it turns out that there is a possibility to have INPUT as a module:
you have to disable VT and TTY (of course), but also enable EXPERT.
I'll leave how to disable VT and TTY as an exercise for the bravest.

Anyway, if INPUT is m, we can still configure HID as y, which is not
correct because hid-input.c depends on the input API, meaning that
vmlinuz can not link.

So: add depends on INPUT too at the HID level, to ensure that if INPUT=m,
HID can only be m or disabled.
