Subject: [RFC PATCH 4/7] ARM: vexpress: use central SMP spin-table routines

This is the second patch involved replacing the use of smp
operations defined under arch/arm/mach-versatile.  Both realview and
vexpress use the same smp_boot_secondary and smp_secondary_init
functions, and those are equivalent to the common ones now available
in arch/arm/kernel/smp.c.

This converts mach-vexpress to use the common routines.
