Many i2c users consider short transfers to be an error and would prefer
getting -EIO instead of a positive return value and having to convert
it to error code by themselves. So let's add the following new helpers:
i2c_master_send_exact()
i2c_master_recv_exact()
i2c_transfer

Tegra only supports, and always enables, device tree. Remove all ifdefs
and runtime checks for DT support from the driver. Platform data is
therefore no longer required. Delete the header that defines it.

Thanks. Please double check that setting NULL is really unneeded for the

Stephen Warren pointed out as part of a code review of another mux
driver that there should be no need to have
"platform_set_drvdata(pdev, NULL)" in the remove function. Get rid of
it in the i2c-mux-gpio driver.
