[ Upstream commit 9caec6620f25b6d15646bbdb93062c872ba3b56f ]
Currently the default clock rates for the HDA and HDA2CODEC_2X clocks are both 19.2MHz. However, the default rates for these clocks should actually be 51MHz and 48MHz, respectively. The current clock settings results in a distorted output during audio playback. Correct the default clock rates for these clocks by specifying them in the clock init table for Tegra210.
