soc/qualcomm/sc7280: Remove NVMe init
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.
