ARM: Enable selection of SMP operations at boot time
Add a new 'smp_init' hook to machine_desc so platforms can specify a
function to be used to setup smp ops instead of having a statically
defined value. The hook must return true when smp_ops are initialized.
If false the static mdesc->smp_ops will be used by default.
Add the definition of "bool" by including the linux/types.h file to
asm/mach/arch.h and make it self-contained.
