mb/google/nissa/var/rull: Change gpio_padbased_override to rtd3

The previous method made cnvi wifi6 configuration cumbersome and unusable.
We abandoned the fw_config judgment method and changed to the better rtd3.

BUG=b:374629673
BRANCH=None
TEST=1. emerge-nissa coreboot chromeos-bootimage
     2. wifi7&wifi6 function is normal
