Subject: [PATCH 3/8] include/linux/kexec.h: move down crash_core.h including

Later generic macros related to crash_core will be added into
<linux/crash_core.h>, and the corresponding arch specific macros will be
added to override them if needed. And Kconfig option KEXEC_CORE selects
CRASH_CORE. So move <linux/crash_core.h> including after <asm/kexec.h>.

And also move the crash_res|low_res and crash_notes delcarations after
<linux/crash_core.h> including because they are all defined in
kernel/kexec_core.c, and note_buf_t is definied in crash_core.h.

This is a preparation patch.
