[PATCH 21/36] drm/tegra: dc: Do not needlessly deassert reset

[Thierry Reding]

From: Thierry Reding <treding@xxxxxxxxxx>

Commit 9c0127004ff4 ("drm/tegra: dc: Add powergate support") changed the
driver's ->probe() implementation to deassert the module reset, and with
there being nobody else to assert it until ->remove() there is no need
to deassert again later on.
