[PATCH v2 0/2] fix tegra-hda on tegra30 devices

[Peter Geis]

The following patches fix tegra-hda on legacy tegra devices.
Two issues were discovered preventing tegra-hda from functioning:
-The hda clocks on tegra30 were assigned to clk_m and running at too low
of a rate to function.
-The tegra-hda encounters an input/output error when opening a stream.

Since the only mainline device that used tegra-hda until recently was the
t124, it is unknown exactly when this was broken. Fortunately a recent
patch was submitted that fixed the issue only on t194 devices. We can
apply it to the tegra30-hda device to resolve the issue across the board.
Note that downstream devices used the spdif device instead of hda for hdmi
audio. The spdif device lacks a driver on mainline.

-Checkpatch seems to have issues finding [1], but git show has no issue.
[1] commit 60019d8c650d ("ALSA: hda/tegra: workaround playback failure on
Tegra194")

Changelog:

v2:
-Added ack and reviewed-by from Jon
-Updated fix to apply to tegra30-hda vice universally (Thanks Jon)
-Updated commit to include comments from hardware team (Thanks Sameer)
-Cleaned up commit messages
