The tegra i2c master controller disables the clock at the end of the initialiation, propably to save some power, and enables it again on each transfer. We don't do this yet and also forgot to enable the clock on resume. Fix this copy-paste error by not disabling the clock after initialization. This didn't striked us yet because suspend/resume hasn't landed in mainline yet, but will soon.
