On Tegra186, other software components may rely on the kernel to
keep Host1x operational even during suspend. As such, as a quirk,
skip asserting Host1x's reset on Tegra186.
We don't need to keep the clocks enabled, as BPMP ensures the clock
stays on while Host1x is being used. On newer SoC's, the reset line
is inaccessible, so there is no need for the quirk.

We should add the fixes tag ...
Fixes: b7c00cdf6df5 ("gpu: host1x: Enable system suspend callbacks")
... because this fixes a suspend regression on Tegra186.
Thierry, would you be able to add the fixes-tag and send out as a fix
for v6.8? Otherwise ...
