arm64: kdump: Update the name of crashk_low_res 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I545H8


CVE: NA

-------------------------------------------------------------------------

To be consistent with the style of other ARCHs such as x86, the kexec
commit b5a34a20984c ("arm64: support more than one crash kernel regions")
requires all crash regions to be named "Crash kernel". Update the name of
crashk_low_res, so that we can directly use the latest kexec tool without
having to maintain a private version.
