ARM: 8101/1: mach-iop13xx: fix possible build failure
After applying patch:
"ARM: 8078/1: get rid of hardcoded assumptions about kernel stack size"
following build failure happens on iop13xx platform:

>> include/linux/rcupdate.h:220:2: error: implicit declaration of function 'preempt_disable' [-Werror=implicit-function-declaration]
preempt_disable();
The problem here is recursive header inclusion which could be avoided by
removing linux/reboot.h from mach/iop13xxx.h.
linux/reboot.h in include/mach/iop13xx.h is needed only for enum reboot_mode,
so header it could be replaced with a enum declaration.
Whatever patch "ARM: 8078/1: get rid of hardcoded assumptions about kernel stack size"
does, I think it's good to avoid unnecessary header inclusion here in any case.
