sun8i: Ippo_q8h_v5_defconfig: Enable SPL support

Now that we've sun8i dram-init support we can enable the SPL for sun8i boards.

While at it also replace CONFIG_DEFAULT_DEVICE_TREE with CONFIG_FDTFILE,
the former is for u-boot's own fdt usage, which we do not use (yet), the later
specifies the fdt to pass to the kernel, which is the one we want.
