This issue is fixed with below commit:

commit 809d9516da73345cca587743b57e45e9095d851e
Author: Laxman Dewangan <ldewangan@nvidia.com>
Date:   Wed Jan 13 00:14:19 2016 -0800

    Input: gpio-keys - allow disabling individual buttons in DT

    Add support to disable buttons from DT via status property if given button
    is not supported on given platforms. This will help re-using existing dtsi
    files across multiple platforms.
