dmaengine: fsl-edma: don't explicitly disable clocks in .remove()

In the Linux kernel, the following vulnerability has been resolved:

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:
         clk_core_disable+0x198/0x1c8 (P)

        ---[ end trace 0000000000000000 ]---
        edma_module already unprepared

         [...]
        ---[ end trace 0000000000000000 ]---

Fix these warnings by removing the unnecessary fsl_disable_clocks() call
in fsl_edma_remove().
