This is function gpio, so presumably board designers could decide to
change the wake gpio to something else, right? I'd prefer we move wake-n
to the board level (idp) as well. gpio79 looks fine as it is muxed to be
the pcie1_clkreqn function, not gpio, so it seems to be a dedicated pin
for this purpose.
