baytrail: use CPU_INTEL_TURBO_NOT_PACKAGE_SCOPED
On baytrail, it appears that the turbo disable setting is actually building-block scoped. One can see this on quad core parts where if enable_turbo() is called only on the BSP then only cpus 0 and 1 have turbo enabled. Fix this by calling enable_turbo() on all non-bsp cpus. BUG=chrome-os-partner:25014 BRANCH=baytrail TEST=Built and booted rambi. All cpus have bit 38 set to 0 in msr 0x1a0.
