How did you compile the U-Boot ? Make sure to clean up your sources
before the build. Try this method:

$ make socfpga_arria5_defconfig
$ make -j9

This will produce the file, I just tested it.

You can try make u-boot-with-spl-dtb.sfp in case you're desperate.

You cannot, since it doesn't contain the DT blob, which describes the
arria5 socdk hardware. The board won't boot without it.

Mixing and matching SPL versions is not supported ; it is well possible
the non-mainline SPL behaves differently or configures the hardware
differently than the mainline u-boot expects (it does), which might
result in odd behavior.
