For booting via UEFI we need to define the fdtfile option so
bootefi has the option to load a fdtfile from disk. For arm64
the kernel dtb is located in a vendor directory so we define
that as nvidia for that architecture.

Without this the aarch64 tegra devices don't find the kernel
device tree when booting using UEFI so fall back to the firmware
DT in U-Boot which alone isn't enough to boot the Linux kernel
and you end up with a boot failure in very early boot due to
being unable to find the architecture timer. This fixes the
issue when booting Fedora using UEFI for me.
