    hwc: Add conditional for use of retire fence

     * This patch is only in AOSP, and requires specific support in the

    hwc: Configure framebuffer before other layers.

    If framebuffer needs to be configured, configure it before all the
    other layers in mdp composition. This helps in cases where we are
    out of SMPs and framebuffer configuration fails owing to that.
    Framebuffer being the fallback path, should always get highest
    priority when reserving SMP blocks

    gralloc: Do not map framebuffer memory unless needed

    The SurfaceFlinger opens the framebuffer module even when it
    isn't necessary. It does this for some legacy hals.
    Due to this we unnecessarily mmap the fb memory in gralloc.
    Do not map this unless the property to use the framebuffer
    memory is set.

    We do further operations in fb_device_open based on the result of
    mapFrameBuffer. However, if mapFrameBuffer is never done, we
    could end up with a random crash when using the info values in
    fb_device_open. Defaulting to an error value avoids this.
