ARM: 9411/1: Switch over to GENERIC_CPU_DEVICES using arch_register_cpu()
Currently, almost all architectures have switched to GENERIC_CPU_DEVICES,
except for arm32. Also switch over to GENERIC_CPU_DEVICES, and provide an
arch_register_cpu() that populates the hotpluggable flag for arm32.
The struct cpu in struct cpuinfo_arm is never used directly, remove
it to use the one GENERIC_CPU_DEVICES provides.
This also has the effect of moving the registration of CPUs from subsys to
driver core initialisation, prior to any initcalls running.
