hw: Fix problem with the A*MPCORE switches in the Kconfig files

A9MPCORE, ARM11MPCORE and A15MPCORE are defined twice, once in
hw/cpu/Kconfig and once in hw/arm/Kconfig. This is only possible
by accident, since hw/cpu/Kconfig is never included from hw/Kconfig.
Fix it by declaring the switches only in hw/cpu/Kconfig (since the
related files reside in the hw/cpu/ folder) and by making sure that
the file hw/cpu/Kconfig is now properly included from hw/Kconfig.
