ASoC: fsl_rpmsg: Check -EPROBE_DEFER for getting clocks
[ Upstream commit 2fbbcffea5b6adbfe90ffc842a6b3eb2d7e381ed ]
The devm_clk_get() may return -EPROBE_DEFER, then clocks
will be assigned to NULL wrongly. As the clocks are
optional so we can use devm_clk_get_optional() instead of
devm_clk_get().
