We are required to boot with eMMC enabled in the BIOS to store modem
calibration data. Thus, it doesn't make sense to enable NVMe at boot
time since we will never boot from NVMe w/o eMMC. We may as well take
the boot time reduction (~100ms) by eliminating NVMe initialization.
BUG=b:185426670, b:254281839
BRANCH=None
TEST=Boot after disabling NVMe and make sure that it still boots
Note that we are able to see a little over 100ms in boot time
savings with this change.
