ARM: decompressor: fix warning introduced in fortify patch
Commit ee333554fed5 ("ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE") introduced a new warning: arch/arm/boot/compressed/misc.c: In function 'fortify_panic': arch/arm/boot/compressed/misc.c:167:1: error: 'noreturn' function does return [-Werror] The simple solution would be to make 'error' a noreturn function, but this causes a prototype mismatch as the function is prototyped in several .c files. So, move the function prototype to a new header. There are also a couple of variables that are also declared in several locations. Clean this up while we are here.
