    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).
