[PATCH 2/4 v7] ASoC: dwc: Do not use devm_clk_get() if using platform data

[Jose Abreu]

When using platform data the devm_clk_get() function is
called causing a probe failure if the clock is not
declared. As we can pass the clock handler by platform
data call only devm_clk_get() when platform data is not
used.
