mb/google/fatcat: Fix GPIO config for headphone jack detection

Browse source 
This commit updates GPP_F17 (CODEC_INIT_N) configuration to fix an issue
with the 3.5mm headphone jack on the I2S codec AIC not detecting
headphone plug/unplug events. Specifically, we need to configure GPP_F17 to have interrupt capability, edge detection to detect plug and unplug events, and power state persistence.

BUG=b:434208278
TEST=After booting to OS, plug and unplug a headphone to the I2S codec
add-in card, headphone is getting detected.
