[PATCH 2/2] ASoC: simple-card-utils: Increase maximum number of links to 128

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

On Tegra186 and later, the number of links can go up to 72, so bump the
maximum number of links to the next power of two (128).

Fixes: f2138aed231c ("ASoC: simple-card-utils: enable flexible CPU/Codec/Platform")
