This patch enables SPI4 on the 96Boards STM32 Sensors Mezzanine.
SPI4 has been broken out to a Grove Connector on the board.
Changes:
- Updated board dts to enable spi4
- Updated board Kconfig
- Updated board documentation
- Update board pinmux
- Updated stm32f4 pinmux header file
- Updated stm32f401 dtsi
- Updated stm32f4 defconfig to enable PORTE GPIO
- Added board to spi_loopback test
Test: spi_loopback test passed

This commit moves DMA parameters previously hard coded in the driver
to the dts.

This commit introduces the possibility to have multiple
device nodes attached to the same I2S controller. For this
purpose a new i2s-device.yaml description has been introduced
with the a 'reg' property to define the logic number of the
device. For example, if two microphones are attached to the
same I2S port (say 1) to achieve stereo audio, the two microphones
might be described in dts as:
&i2s1 {
status = "ok";
mic@0 {
compatible = "...";
reg = <0>;
label = "...";
};
mic@1 {
compatible = "...";
reg = <1>;
label = "...";
};
};

Newer DTC now warns about mismatch between the reg and unit-address.
Most of these cases are due to case not matching, so fix thoses so
everything is lowercase.

Add I2S bus initial support to stm32f4 SOC family.
On stm32f4 the I2S shares same controller as SPI, so
the declarations have been adapted from SPI ones.

To move forward and remove use of Kconfig in dts files lets just create
SoC specific dtsi files that the boards can include. We also seperate
out the F4 dtsi files into their own dir.
