This small series addresses a couple of runtime PM issues I've spotted
while running 4.18 on a Chromebook Plus (kevin, rk3399) platform, and
specifically doing kexec.

In order to avoid making a complete mess of the IOMMU code, Heiko has
requested that all RK platforms would select CONFIG_PM, which
simplifies a lot of things. I've kept 32 and 64bit patches separate,
but feel free to squash them into on if that's more convenient.

Note that even with these patches, kexec is still fairly broken on
rk3399, as the VOP is never turned off (see [1] for a fix).

* From v1:
  - Collected RBs from Heiko
  - Added two patches forcing CONFIG_PM on all Rockchip platforms at
    Heiko's request, following the example set by Tegra platforms.

Thanks, applied to our next/late branch which I plan to send in tomorrow.
