rockchip/rk3399: improve pmu powermode configure when suspend 

we need to enable PMU_WKUP_RST_EN for pmu powermode configure, since
enable wakeup reset will hold the soc status, so the SOC will not affect
by some power or other single glitch when resume, and keep the soc in the
right status. And it not need to enable DDRIO_RET_HW_DE_REQ, the ddr resume
will do it manual.
