Move the timer from CPUAlphaState to AlphaCPU to avoid the pointer being zero'ed once we implement reset. Would cause a segfault in sys_helper.c:helper_set_alarm(). This also simplifies timer initialization in Typhoon. Signed-off-by: Andreas Färber <afaerber@suse.de> Acked-by: Richard Henderson <rth@twiddle.net>
