When building the i2s tests on 96b_argonkey we get the following
warnings:
drivers/dma/dma_stm32.c: In function 'dma_stm32_configure':
drivers/dma/dma_stm32.c:181:2: error: 'periph_addr_adj' may be used
uninitialized in this function [-Werror=maybe-uninitialized]
181 | switch (increment) {
| ^~~~~~
drivers/dma/dma_stm32.c:161:2: error: 'memory_addr_adj' may be used
uninitialized in this function [-Werror=maybe-uninitialized]
161 | switch (increment) {
| ^~~~~~
Fix by initialzing periph_addr_adj and memory_addr_adj to 0.
