memory: tegra: Introduce memory client hot reset
In order to reset busy HW properly, memory controller needs to be involved, otherwise it is possible to get corrupted memory or hang machine if HW was reset during DMA. Introduce memory client 'hot reset' that will be used for resetting of busy HW. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
