Subject: [PATCH] dmaengine: fsl-edma: Fix clk leak on alloc_chan_resources
failure

When fsl_edma_alloc_chan_resources() fails after clk_prepare_enable(), the error paths only free IRQs and destroy the TCD pool, but forget to call clk_disable_unprepare(). This causes the channel clock to remain enabled, leaking power and resources.

Fix it by disabling the channel clock in the error unwind path.
