This driver supports ST Microelectronics digital pdm microphones
(MPxxDTyy) connected through different peripherals. Currently only
I2S is supported.
The driver makes use internally of the OpenPDM2PCM library
to convert the PDM audio stream to PCM. Currently the
oversampling factor is fixed to 64.

Update Kconfig for tlv320dac audio DAC to include GPIO
as a dependency. The codec driver now uses GPIO driver
to control the RESET for the DAC.

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

Use ARRAY_SIZE helper macro to compute size of array rather
than hardcoding.
Also, remove unnecessary variable to store the size which is
now useless.
Found using Coccinelle.
