ASoC: tegra: Fix uninitialized flat cache warning in tegra210_ahub
The tegra210_ahub driver started triggering a warning after commit
e062bdfdd6ad ("regmap: warn users about uninitialized flat cache"),
which flags drivers using REGCACHE_FLAT without register defaults.
Since the driver omits default definitions because its registers are
zero initialized, the following warning is shown:
WARNING KERN tegra210-ahub 2900800.ahub: using zero-initialized flat cache, this may cause unexpected behavior
Switch to REGCACHE_FLAT_S which is the recommended cache type for
sparse register maps without defaults. This cache type initializes
entries on-demand from hardware, eliminating the warning while using
memory efficiently.
