How are the pin muxes normally configured in ACPI?  All of our GPIOs 
have a pinmux on them, and so if you want to use the pin for the 
non-default functionality, you need to configure the mux.  Isn't that 
supposed to happen with the through the pinctrl driver?  That is, when 
the kernel parses the ASL, and it seems a command to configure pin #3 to 
function #4, it calls the local pinctrl driver to do that?
