Fix for bugs described in:
https://github.com/zephyrproject-rtos/zephyr/issues/59803
1. the size argument passed to i2s_write() was being ignored.
change the code so that the size is queued with the
tx mem_block and the dma transfer is configured with this
size.
2. change how CONFIG_I2S_MCUX_FLEXCOMM_RX_BLOCK_COUNT and
CONFIG_I2S_MCUX_FLEXCOMM_TX_BLOCK_COUNT are used so that
the queue buffers are allocated correctly when the two
config values are not the same
3. set source_data_size and dest_data_size to be the same
since the DMA controller can only set one size per
DMA transfer. the driver was already computing a dest_data_size
but always passing 1 for the source_data_size.
For I2S RX case, I think source_data_size should be
set to the expected FIFO read size instead of dest_data_size.
Also some smaller improvements like:
* don't allocate two dma_blocks for tx in the static dev_mem
when it only needs one
* memset both rx_dma_blocks together instead of separtely
* set dma_cfg block_count for tx and rx statically instead
of at runtime
