Subject: [PATCH 5.1 07/55] clk: tegra210: Fix default rates for HDA clocks

From: Jon Hunter <jonathanh@...dia.com>

commit 9caec6620f25b6d15646bbdb93062c872ba3b56f upstream.

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.
