[PATCH] pmdomain: tegra: Add GENPD_FLAG_NO_STAY_ON flag

[PATCH] pmdomain: tegra: Add GENPD_FLAG_NO_STAY_ON flag

[Jon Hunter]

Commit 13a4b7fb6260 ("pmdomain: core: Leave powered-on genpds on until
late_initcall_sync") kept power-domains on longer during boot which is
causing some GPU related tests to fail on Tegra234. While this is being
investigated, add the flag GENPD_FLAG_NO_STAY_ON for Tegra devices to
restore the previous behaviour to fix this.

Applied for fixes and by adding a stable tag, thanks!

Kind regards
