Make this_cpu is arch independent and up_cpu_index do that.
In AMP mode, up_cpu_index() may return the index of the physical core.

HPET can be used as system clock for x86_64
to set HPET as system clock you have to enable:
CONFIG_ONESHOT=y
CONFIG_ALARM_ARCH=y
CONFIG_INTEL64_ONESHOT=y
CONFIG_ARCH_INTEL64_HPET_ALARM=y

Intel64 can now boot application cores which is needed for SMP
IMPORTANT: CONFIG_BOARD_LOOPSPERMSEC must be properly configured,
otherwise AP boot sequence can fail due too short delays during the AP startup

Then we can easily refer to private CPU data using the GS segment.
