When building the kernel with sparse enabled 'C=1' the following
warnings can be seen:
arch/arm64/kernel/setup.c:58:13: warning: symbol '__fdt_pointer' was not declared. Should it be static?
arch/arm64/kernel/setup.c:84:25: warning: symbol 'boot_args' was not declared. Should it be static?
Rework so the variables are exported, since these two variable are
created and used in setup.c, also used in head.S.
