Default UBUNTU: SAUCE: Input: ALPS - Enable Intellimouse mode for Lenovo Zhaoyang E47

The quirk enables the edge-scrolling function of the touchpad.
This patch depends on the following sauce patch:

commit 83ccc92aa7bc9b9d47fc31a7b54e663fb9a3d992
Author: Rezwanul Kabir <Rezwanul_Kabir@dell.com>

Add support for Intellimouse Mode in ALPS touchpad on Dell E2 series Laptops

Resending modified patch to fix suspend/resume issues and restricting the
quirks to Dell portables only.

Dell E2 series laptops ( M4500, E6510, E6410 etc.) have ALPS touchpads
which are enabled by default as 3-byte generic PS/2 mouse mode. This
patch enables the 4-byte "Intellimouse Mode" ( e.g scrolling support).
