[Maxim Polyakov (Code Review)]

mb/intel/cedarisland_crb: 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 this fields to 0.
