x86/kdump: Remove the backup region handling
When the crashkernel kernel command line option is specified, the low
1M memory will always be reserved now. Therefore, it's not necessary to
create a backup region anymore and also no need to copy the contents of
the first 640k to it.
Remove all the code related to handling that backup region.
