Subject: [PATCH 5/7] dma: fsl-edma: Move error handler out of header file

Move fsl_edma_err_chan_handler from an inline function in the header
to a proper function in fsl-edma-common.c. This prepares for MCF
ColdFire eDMA support where the error handler needs to be called from
the MCF-specific error interrupt handler.

No functional change for existing users.
