mb/google/brya/primus: add NVMe power and reset pin to early_gpio_table
NVMe needs extra time to run boot process, enable power and deassert
reset for NVMe earlier in the boot flow that primus can successfully
boot into OS with non-serial coreboot.
BUG=b:199967106
TEST=USE="project_primus" emerge-brya coreboot and verify it builds
without error.
