s390/boot: add missing declarations and includes

Add __swsusp_reset_dma declaration to avoid the following sparse warnings:
arch/s390/kernel/setup.c:107:15: warning: symbol '__swsusp_reset_dma' was not declared. Should it be static?
arch/s390/boot/startup.c:52:15: warning: symbol '__swsusp_reset_dma' was not declared. Should it be static?

Add verify_facilities declaration to avoid the following sparse warning:
arch/s390/boot/als.c:105:6: warning: symbol 'verify_facilities' was not declared. Should it be static?

Include "boot.h" into arch/s390/boot/kaslr.c to expose get_random_base
function declaration and avoid the following sparse warning:
arch/s390/boot/kaslr.c:90:15: warning: symbol 'get_random_base' was not declared. Should it be static?
