ASoC: tegra: Revert fix for uninitialized flat cache warning in tegra210_ahub 



Commit 4d4021b0 ("ASoC: tegra: Fix uninitialized flat cache warning
in tegra210_ahub") attempted to fix the uninitialized flat cache warning
that is observed for the Tegra210 AHUB driver. However, the change broke
various audio tests because an -EBUSY error is returned when accessing
registers from cache before they are read from hardware. Revert this
change for now, until a proper fix is available.
