soc/qualcomm/sc7280: Skip PCIe ops for eMMC SKUs

On Herobrine, we will determine if we have an NVMe device based on SKU
id.  Basically, if bit 0 is 2 (or Z), then we know that we have an
NVMe device and thus will need to go through PCIe initialization.
Otherwise, we know that we are booting an eMMC device.

BUG=b:254281839
BRANCH=None
TEST=build firmware image and boot and make sure we can boot up Tested
     on villager, which does not have NVMe and made sure that it boots
     still.  Check cbmem dump to make sure that device configuration
     entry is still low since it's not initializing PCIe devices:

     40:device configuration 730,203 (1,295)
