[PATCH 2/5] ASoC: fsl_sai: Use optional clock getter for MCLKs

[phucduc.bui@gmail.com]

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

The current code uses devm_clk_get() and sets the clock pointer
to NULL when it returns an error. However, this silently ignores
errors such as -EPROBE_DEFER, allowing the driver to continue
probing without the requested clock.

Use devm_clk_get_optional() to handle missing optional clocks
automatically, and dev_err_probe() to properly propagate other
errors, including -EPROBE_DEFER.
