Subject: [PATCH] ata: libahci: ignore staggered spin-up

Change libahci to ignore firmware's staggered spin-up flag. End-users
who wish to honor firmware's SSS flag can add the following kernel
parameter to a new file at /etc/kernel/cmdline.d/ignore_sss.conf:
    libahci.ignore_sss=0

And then run
    sudo clr-boot-manager update
