Pull pmdomain updates from Ulf Hansson:
 "pmdomain core:
   - Leave powered-on genpds on until ->sync_state() or late_initcall_sync
   - Export a common ->sync_state() helper for genpd providers
   - Add generic ->sync_state() support
   - Add a bus/driver for genpd provider-devices
   - Introduce dev_pm_genpd_is_on() for consumers

  pmdomain providers:
   - cpuidle-psci: Drop redundant ->sync_state() support
   - cpuidle-riscv-sbi: Drop redundant ->sync_state() support
   - imx: Set ISI panic write for imx8m-blk-ctrl
   - qcom: Add support for Glymur and Milos RPMh power-domains
   - qcom: Use of_genpd_sync_state() for power-domains
   - rockchip: Add support for the RK3528 variant
   - samsung: Fix splash-screen handover by enforcing a ->sync_state()
   - sunxi: Add support for Allwinner A523's PCK600 power-controller
   - tegra: Opt-out from genpd's common ->sync_state() support for pmc
   - thead: Instantiate a GPU power sequencer via the auxiliary bus
   - renesas: Move init to postcore_initcalls
   - xilinx: Move ->sync_state() support to firmware driver
   - xilinx: Use of_genpd_sync_state() for power-domains

  pmdomain consumers:
   - remoteproc: imx_rproc: Fixup the detect/attach procedure for
     pre-booted cores"
