 DTS and DTSO needs to be pre-processed by cpp as they use #include
directives, you can have a look at sys/tools/fdt/make_dtb.sh and
make_dtbo.sh
 If you modify the DTS simply running make buildkernel will compile the
new one, just make sure to put it on the FAT32 partition in
dts/allwinner as we need it loaded by u-boot and it can't read ufs.
