[PATCH V4 Resend] ZBOOT: fix stack protector in compressed boot phase

by Huacai Chen

Call __stack_chk_guard_setup() in decompress_kernel() is too late that stack checking always fails for decompress_kernel() itself. So remove __stack_chk_guard_setup() and initialize __stack_chk_guard before we call decompress_kernel(). Original code comes from ARM but also used for MIPS and SH, so fix them together. If without this fix, compressed booting of these archs will fail because stack checking is enabled by default (>=4.16). V1 -> V2: Fix build on ARM. V2 -> V3: Fix build on SuperH. V3 -> V4: Initialize __stack_chk_guard in C code as a constant.
