On Tegra186, secure world applications may need to access host1x
during suspend/resume, and rely on the kernel to keep Host1x out
of reset during the suspend cycle. 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.
