[coreboot-gerrit] Change in coreboot[master]: mb/ocp/tiogapass/gpio: undo set trig and bufdis for NF pads

[Maxim Polyakov (Code Review)]

Hello build bot (Jenkins), Jonathan Zhang, Angel Pons, Bryant Ou,

I'd like you to reexamine a change. Please visit

mb/ocp/tiogapass/gpio: undo set trig and bufdis for NF pads

According to the documentation [1], RX Level/Edge Configuration (trig)
and GPIO Tx/Rx Buffer Disable (bufdis) [2] settings are not applicable
in native mode and BIOS does not need to configure them. Therefore,
there is no need to configure this in gpio.h using PAD_CFG_NF_BUF_TRIG
macros. Use PAD_CFG_NF instead and set these fields to 0.
