Tegra2: mmc: Add data transfer completion timeout
Currently when no expected completion condition occures in the
mmc_send_cmd while loop that is waiting for a data transfer to
complete the MMC driver just hangs.
This patch adds an arbitrary 2 second timeout. If nothing we
recognize occures within 2 seconds some diagnostic information
is printed and we fail out.
