[PATCH 3/7] kexec: Move crash kernel area placement and size detection to is_crashkernel_mem_reserved()

[Daniel Kiper <daniel.kiper-QHcLZuEGTsvQT0dZR+AlfA@public.gmane.org>]

Move crash kernel area placement and size detection
from get_crash_memory_ranges() to is_crashkernel_mem_reserved().
Former one will not be used by fixed Xen kdump support.
