[PATCH 5/5] ASoC: mediatek: mt8186: Propagate clock lookup errors

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

The driver currently clears the clock pointer when devm_clk_get()
fails and continues initialization. The clock operations later in the
driver do not check for missing clocks before using them.

Return the error from devm_clk_get() instead of continuing with an
invalid clock state. Use dev_err_probe() to report the error while
preserving the original error code.
