Subject: [PATCH linux-next v3 13/14] arm, crash: wrap crash dumping code into crash related ifdefs

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.

Signed-off-by: Baoquan He <bhe@...hat.com>
---
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.
