[PATCH v6 07/11] ASoC: renesas: fsi: Use devm_clk_get_optional() for optional clocks

[phucduc.bui@gmail.com]

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

The xck, ick, and div clocks are optional. Switch from devm_clk_get()
to devm_clk_get_optional() to correctly handle cases where these clocks
are missing.
