Fix cpu_arm_handle_mmu_fault warning

This patch fixes:

/scratch/froydnj/qemu.git/target-arm/helper.c:451: warning: no previous prototype for 'cpu_arm_handle_mmu_fault'

by moving the declaration of the function to cpu.h from exec.h.  cpu.h
seems to be the place most other ports declare the corresponding
function.
