drivers: dma: i2s: stm32: I2S Master DMA support

When configuring the I2S peripheral as a master, the DMA channel
direction must be configured to transfer data from memory to the
peripheral.

Currently the configuration of channel direction is always set for
peripheral to memory regardless of whether it is the TX or the RX
channel.
