sunxi: Ensure that 'mksunxiboot' tool produces deterministic output
Currently some uninitialized padding bytes are written to the output
file, as can be confirmed with valgrind:
$ valgrind tools/mksunxiboot spl/u-boot-spl.bin spl/sunxi-spl.bin
==5581== Syscall param write(buf) points to uninitialised byte(s)
==5581== at 0x4F0F940: __write_nocancel (in /lib64/libc-2.20.so)
==5581== by 0x400839: main (in /tmp/u-boot/tools/mksunxiboot)
==5581== Address 0xffeff5d3c is on thread 1's stack
==5581== in frame #1, created by main (???)
This patch fixes the problem by clearing the whole structure instead
of just a portion of it.
