Compilation/Build fix when CONFIG_KEXEC is enabled
This is caused because of :
a) commit 6c4d635cb3ac ("Revert "arm64: kill flush_cache_all()"")
included internally adds asm code for cpu_soft_restart and defined
in proc-fns.h. It was added so that ramdump contains all dirty
cache data and cache flush in reboot.
b) commit f9076ecfb121 ("arm64: Add back cpu reset routines") from
upstream adds cpu_soft_restart in cpu_reset.h and hooks it up to
hyp-stub. This patch's main intention was to add support for kexec.
The patch chooses to rename function in (b) because it's intended
use is for kexec.
