Subject: arm, crash: wrap crash dumping code into crash related ifdefs
Date: Mon, 15 Jan 2024 22:32:19 -0500
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.
