dmaengine: fsl-edma: Remove redundant dev_err() for platform_get_irq()

Since commit 7723f4c5 ("driver core: platform: Add an error message
to platform_get_irq*()") and commit 2043727c ("driver core:
platform: Make use of the helper function dev_err_probe()"), there is
no need to call the dev_err() function directly to print a custom
message when handling an error from platform_get_irq() function as it is
going to display an appropriate error message in case of a failure.
