mb/google/brya/variants/taeko: add NVMe GPIOs 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 taeko can successfully
boot into OS with non-serial coreboot.

BUG=b:199969366 & b:200711149
TEST=Build FW and test with non-serial FW reboot 20 times pass.
