nb/intel/sandybridge: Refine power-down mode logic
When memory is running at fast frequencies, power-down modes can lessen system stability. Check tXP and tXPDLL values and use safer power down modes if their values are high. Do not use APD with DLL-off on mobile: vendor firmware does not use it, and it can influence system stability.
