mb/google/brya/var/primus: Fix some GPIO programming

During the initial review, a few unused GPIOs that were inherited
from the baseboard were missed, so this CL programs them as PAD_NC.
   GPP_B2  => non-use
   GPP_B15 => non-use (for FPR)
   GPP_D3  => non-use (Test point)
   GPP_E21 => non-use (for LCLW Detect)

BUG=b:211721639
TEST= USE="project_primus" emerge-brya coreboot and verify it builds without error.
