There are two sleep related pins on rk3399: ap_pwroff and ddrio_pwroff. Let's add the definition of these two pins to rk3399's main dtsi file so that boards can use them. These two pins are similar to the global_pwroff and ddrio_pwroff pins in rk3288 and are expected to be used in the same way: boards will likely want to configure these pinctrl settings in their global pinctrl hog list. Note that on rk3288 there were two additional pins in the "sleep" section: "ddr0_retention" and "ddr1_retention". On rk3288 designs these pins appeared to actually route from rk3288 back to rk3288. Presumably on rk3399 this is simply not needed since the pins don't appear to exist there.
