[PATCH v8 07/15] memory: tegra20-emc: Increase handshake timeout

[Dmitry Osipenko]

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.
