[PATCH v8 32/34] ARM: tegra: Add Memory Client resets to Tegra20 GR2D, GR3D and Host1x

[Dmitry Osipenko <digetx@gmail.com>]

Memory access must be blocked before hardware reset is asserted and before
power is gated, otherwise a serious hardware fault is inevitable. Add
reset for memory clients to the GR2D, GR3D and Host1x nodes.
