Revert "HID: input: Create a utility class for counting scroll events"

Browse source 
This reverts commit 1ff2e1a44e.

It turns out the current API is not that compatible with
some Microsoft mice, so better start again from scratch.

* @microns_per_hi_res_unit: the amount moved by the user's finger for each
* high-resolution unit reported by the mouse, in
* microns.
* @resolution_multiplier: the wheel's resolution in high-resolution mode as a
* multiple of its lower resolution. For example, if
* moving the wheel by one "notch" would result in a
* value of 1 in low-resolution mode but 8 in
* high-resolution, the multiplier is 8.
* @remainder: counts the number of high-resolution units moved since the last
* low-resolution event (REL_WHEEL or REL_HWHEEL) was sent. Should
* only be used by class methods.
