soc/intel/common: gpio_defs: set trig to disable in PAD_CFG_GPO*
According to the documentation [1], by default the RX Level/Edge Trig
Configuration set to disable (2h = Drive '0') for each pad. Since this
setting doesn't matter for the GPO pad, there is no need to change the
default value for such pads. The patch updates PAD_CFG_GPO* macros to
set trig to disable. It also resolves some problems of creating the
PCH/SoC pads configuration based on information from the inteltool
dump [2,3]
