[PATCH 1/3] ASoC: jz4725b: Convert to devm_clk_get_enabled()

[Jihed Chaibi]

The clock is obtained with devm_clk_get() in the platform probe, then
manually enabled in the component probe and disabled in the component
remove without checking the return value of clk_prepare_enable().

Use devm_clk_get_enabled() instead, which combines the get, prepare and
enable operations into one call whose lifetime is tied to the device.
This removes the need for explicit enable/disable in the component
probe/remove callbacks, and ensures that clock enable failures are
propagated as errors rather than silently ignored.

Remove the now-unused struct clk pointer from struct jz_icdc and drop
the empty component remove callback.
