dmaengine: fsl-edma: don't explicitly disable clocks in .remove()
The clocks in fsl_edma_engine::muxclk are allocated and enabled with
devm_clk_get_enabled(), which automatically cleans these resources up,
but these clocks are also manually disabled in fsl_edma_remove(). This
causes warnings on driver removal for each clock:
edma_module already disabled
WARNING: CPU: 0 PID: 418 at drivers/clk/clk.c:1200 clk_core_disable+0x198/0x1c8
[...]
Call trace:

edma_module already unprepared

---[ end trace 0000000000000000 ]---
Fix these warnings by removing the unnecessary fsl_disable_clocks() call
in fsl_edma_remove().
