PATCH 1/1 x86: Fix Linux v4.7+ zimage booting (update bootparam.h)

Booting Linux kernel v4.7+ does not work since commit 974f221c "x86/boot: Move compressed kernel to the end of the decompression buffer".

This patch adds the latest version of the setup_header struct, adding "init_size" which is needed since this commit referenced above. With this patch, booting Linux v4.8-rc8 does work again on x86 boards.
