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.

The advent of big.LITTLE ARM platforms requires the kernel to be able
to identify the MIDRs of all online CPUs upon request. MIDRs are stashed
at boot time so that kernel subsystems can detect the MIDR of online CPUs
by simply retrieving per-CPU data updated by all booted CPUs.

The file arch/arm/include/asm/cpu.h needs to include 'linux/cpu.h' to
meet its dependency. Otherwise when using "struct cpuinfo_arm" and
including just 'asm/cpu.h' throws below error -
arch/arm/include/asm/cpu.h:16: error: field 'cpu' has incomplete type
To fix this otherway, one can also include both linux/cpu.h and
asm/cpu.h but it shoudn't be that way. So this patch fixes this by
including the linux/cpu.h in asm/cpu.h, so that including alone
asm/cpu.h is enough.

Move platform independent header files to arch/arm/include/asm, leaving
those in asm/arch* and asm/plat* alone.
