[PATCH 03/46] kernel: Move prototype declaration to header file include/linux/cpu.h

[Rashika Kheria]

Add prototype declaration to header file include/linux/cpu.h because
they are used by more than one file.

This eliminates the following warning in kernel/cpu.c:
kernel/cpu.c:512:13: warning: no previous prototype for âarch_enable_nonboot_cpus_beginâ [-Wmissing-prototypes]
kernel/cpu.c:516:13: warning: no previous prototype for âarch_enable_nonboot_cpus_endâ [-Wmissing-prototypes]
