pmdomain: tegra: Add GENPD_FLAG_NO_STAY_ON flag

commit c98c99d5dbdf9fb0063650594edfd7d49b5f4e29 upstream.

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.
