ASoC: tegra_alc5632: assume CONFIG_OF, and other cleanup

Browse source 
Tegra only supports, and always enables, device tree. Remove all runtime
checks for DT support from the driver.

Also, various minor cleanups so that the probe() body more closely
resembles other drivers, for easier comparison.
