Now crash codes under kernel/ folder has been split out from kexec
code, crash dumping can be separated from kexec reboot in config
items on arm with some adjustments.

Here use CONFIG_CRASH_RESERVE ifdef to replace CONFIG_KEXEC ifdef.

v2->v3:
- Fix the lkp reported issue by using CONFIG_CRASH_RESERVE ifdef,
giving up the earlier IS_ENABLED(CONFIG_CRASH_RESERVE) checking
in v2.
