Subject: [PATCH 0/2] iommu/rockchip: Runtime PM fixes

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.

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