ASoC: Tegra: Rename harmony.c to tegra_wm8903.c

Soon, this machine driver will be updated to handle a number of Tegra boards
using the WM8903 codec. Rename the file in advance to reflect this.

Fix the content of tegra_wm8903.c to match the rename; replace references
to Harmony board with something more generic.

* s/struct tegra_harmony/struct tegra_wm8903/
* s/harmony/machine/ # variable name
* Similar rename for some functions
* Similar comment fix
* Similar MODULE_DESCRIPTION fix
