Dmitry Osipenko b56563d013 memory: tegra: Increase handshake timeout on Tegra20
Turned out that it could take over a millisecond under some circumstances,
like running on a very low CPU/memory frequency. TRM says that handshake
happens when there is a "safe" moment, but not explains exactly what that
moment is. Apparently at least memory should be idling and thus the low
frequency should be a reasonable cause for a longer handshake delay.
