* @reset_gpio: AC97 reset gpio (normally gpio113 or gpio95)
* a -1 value means no gpio will be used for reset
* reset_gpio should only be specified for pxa27x CPUs where a silicon
* bug prevents correct operation of the reset line. If not specified,
* the default behaviour on these CPUs is to consider gpio 113 as the
* AC97 reset line, which is the default on most boards.
