Port the I2S and DMIC drivers to the new timeout API so that they do
not need to enable legacy timeouts.

move misc/__assert.h to sys/__assert.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Fixed an issue I2S wouldn't resume when started after a stop
Added code to empty the TX/RX FIFOs upon stop
TX stop is achieved by letting FIFO underrun, then changing state in ISR
RX FIFO is read until empty when RX is stopped

Added bidirectional I2S support for Intel S1000
- Added implementation for I2S receive mode
- Extended driver instances to support 3 I2S ports
- Added DMA channel mappings for upto 4 I2S ports
- Utilized k_msgq to track buffers through the driver
- Allocate buffers for audio reception in the driver
- Free buffers after audio transmission in the driver
- Perform buffer reload for DMA after every reception/transmission
- Removed unused Kconfig variables
- I2S_CAVS_TX_BLOCK_COUNT
- I2S_CAVS_RX_BLOCK_COUNT

The dma_tx_callback() function signature is different than the one
required by struct dma_config. So change the signature to fix
a compiler warning.

The return of memset is never checked. This patch explicitly ignore
the return to avoid MISRA-C violations.
The only directory excluded directory was ext/* since it contains
only imported code.

Remove I2S resource ownership configuration.
Such configuration will be done in an SoC level
initialization routine

Added support for fractional division of reference clock to obtain
I2S bit clocks
For example:
If reference clock is 38.4MHz and
if the I2S format is 2ch, 32bits per channel, 48KHz sample rate,
the bit clock frequency has to be 2*32*48K = 3.072MHz
38.4MHz/3.072MHz = 12.5 (a fraction)

The driver was using CONFIG_I2S_1_IRQ_PRI which doesn't exist. It
should use CONFIG_I2S_CAVS_1_IRQ_PRI.
