    Input: i8042 - add quirk for ASUS Zenbook UX425QA_UM425QA

    The ASUS Zenbook UX425QA_UM425QA fails to initialize the keyboard after
    a cold boot.

    A quirk already exists for "ZenBook UX425", but some Zenbooks report
    "Zenbook" with a lowercase 'b'. Since DMI matching is case-sensitive,
    the existing quirk is not applied to these "extra special" Zenbooks.

    Testing confirms that this model needs the same quirks as the ZenBook
    UX425 variants.
