ALSA: hda/proc: show GPI and GPO state in codec proc output
print_gpio() prints the GPIO capability header and the bidirectional
GPIO state, but it never reports the separate GPI and GPO pins even
though AC_PAR_GPIO_CAP exposes their counts.
The HD-audio specification defines dedicated GPI and GPO verbs
alongside the GPIO ones, so codecs with input-only or output-only
general-purpose pins currently lose that state from
/proc/asound/card*/codec#* altogether.
Add the missing read verb definitions and extend print_gpio() to dump
the GPI and GPO pins, too, while leaving the existing IO[] output
unchanged.
