i2c: imx: zero-initialize dma_slave_config for eDMA

commit 66d88e16f204 ("dmaengine: fsl-edma: read/write multiple registers
in cyclic transactions") causes fsl_edma_fill_tcd() to read
dst_port_window_size and src_port_window_size when building transfer
control descriptors.

Initialize the structure so unset fields are explicitly zero.
