[ARM] tegra_i2s_audio: add more elaborate error counts

Browse Source 
This patch replaces the error counter with two separate error counters, one for
late dma callbacks, and another for overruns (during recording) or underruns
(during playback).  The ioctls TEGRA_AUDIO_IN_GET_ERROR_COUNT and
TEGRA_AUDIO_OUT_GET_ERROR_COUNT now take a pointer to a struct containing both
error counters.
