Support UFS build as it's more stable compared with NVMe build, meanwhile after dtb moved to spinor, there will sector size mismatch issue which need more time for potential design adjustment of image generation.
Sector size, PCAT tool will check the sector size mismatch between image and storage, QDL tool looks not as it flash well with dtb.bin sector size 512 in spinor.
spinor => 4096, UFS => 4096, NVMe => 512
vfat image size for NVMe (such as dtb.bin and efi.bin) : QCOM_VFAT_SECTOR_SIZE = 512.
vfat image size for UFS (dtb.bin/efi.bin): QCOM_VFAT_SECTOR_SIZE = 4096.
On NVMe build, observed stable issue with ~3% probability due to NVMe caused kernel panic. which is not observed on UFS build.
