The struct ring_buf is renamed to struct ring_buffer to be able to coexist
with the sys/ring_buffer.h header file.

Now that device_api attribute is unmodified at runtime, as well as all

src_addr_increment, dst_addr_increment, fifo_threshold and priority
are missing as parameters for configuring DMA. This commit adds them
to the driver.

The i2s driver assumes the tx channel and rx channel of dma are using
the same dma controller. This commit changes it to be able to use
different dma controllers.

STM32 I2S driver implementation. It has been designed in the most
generic way possible, with the possibility of using it in master/slave
and rx/tx mode. Currenty it has been tested for master rx mode only
using the microphone on ArgonKey board.
The configuration file permits to compile it for STM32F4xx product
family only, but it should be easy to extend it also for other
families.
It supports all 5 STM32F4xx I2S controllers (I2S 1/4/5 on APB2 and
I2S 2/3 on APB1).
It makes uses of the available DMA channels for rx/tx streams.
The clock source can be selected among one of the following two choices:
- PLLI2S pll, with possibility to configure PLLM/PLLN/PLLR
- HSE/HSI clock
Interrupt is triggered only in case of errors (FRM/OVR/UDR).
