[PATCH v5 05/17] spi: imx: Simplify clock handling with devm_clk_get_enabled()

[Pei Xiao]

Replace devm_clk_get() followed by clk_prepare_enable() with
devm_clk_get_enabled() for both "ipg" and "per" clocks. This reduces
boilerplate code and error handling, as the managed API automatically
disables the clocks when the device is removed or if probe fails.

Remove the now-unnecessary clk_disable_unprepare() calls from the
probe error paths.
