gpu: host1x: Rename "parent" to "host"

Rename the host1x clients' parent to "host" because that more closely
describes what it is. The parent can be confused with the parent device
in terms of the device hierarchy. Subsequent patches will add a new
member that refers to the parent in that hierarchy.

Merge tag 'drm/tegra/for-5.5-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next

drm/tegra: Changes for v5.5-rc1

The bulk of these changes is the addition of DisplayPort support for
Tegra210, Tegra186 and Tegra194. I've been running versions of this for
about three years now, so I'd consider these changes to be pretty
mature. These changes also unify the existing eDP support with the DP
support since the programming is very similar, except for a few steps
that can be easily parameterized.

The rest are a couple of fixes all over the place for minor issues, as
well as some work to support the IOMMU-backed DMA API, which in the end
turned out to also clean up a number of cases where the DMA API was not
being used correctly.

Rename paddr -> iova and vaddr -> virt to make it clearer how these
