ARM: dts: rockchip: add RK3288 suspend support
add pmu sram node for suspend, add global_pwroff pinctrl. The pmu sram is used to store the resume code. global_pwroff is held low level at work, it would be pull to high when entering suspend. reference this in the board DTS file since some boards need it.
