pmdomain:rockchip: Fix init genpd as GENPD_STATE_ON before regulator ready
RK3588_PD_NPU initialize as GENPD_STATE_ON before regulator ready.
rknn_iommu initlized success and suspend RK3588_PD_NPU. When rocket
driver register, it will resume rknn_iommu.
If regulator is still not ready at this point, rknn_iommu resume fail,
pm runtime status will be error: -EPROBE_DEFER.
This patch set pmdomain to off if it need regulator during probe,
consumer device can power on pmdomain after regulator ready.
