After this commit was added the I2S driver is no longer working and so fix this by correcting the default value for this register and explicitly configuring the I2S_ENABLE register when runtime resuming the I2S device. The I2S_ENABLE register offset is different on Tegra264 devices than other Tegra devices and so add a 'enable_reg' variable to the SoC data structure to specify the offset for different SoC devices.
