pmdomain: renesas: Adjust the waiting time to cover the worst case
Description in HWM rev0.51E, 9.4 Usage notes, page 455 tells
"It takes several hundreds of microseconds to shutting off and
resuming power domain. Because actual time required for
shutting off and resuming depends on the status of on-board
power line, shutoff/resume time is not guaranteed by
electrical specification"
Let's assume the safe value of waiting is about 1000us.
