Initialize the audio clock tree appropriately for some reasonable rate. This makes sure the PLLs etc. are actually programmed to something reasonable when the audio driver is loaded.

Signed-off-by: Stephen Warren swarren@nvidia.com --- v2: Use 44100 as the default rate, not 48000, since it's more common, and consistent with the clock tables in board-dt-tegra*.c.

This patch is ordered after the patch I just sent to add Tegra30 support to the utils file. However, the dependency is just for context; this should be independent from that patch.
