quanta q71l not booting with 4.13

[Patrick Venture]

Hi;

So, i have a couple theories to test but before I ran them down I
figured I'd just ask here.  The quanta-q71l won't boot if the BMC is
running the 4.13 kernel from openbmc.  I'm theorizing that the spi mux
is flipped somehow (maybe a default pin value is getting flipped) or
something else is preventing the host from reading its flash.

Has anyone experienced anything like this on their platform?
