stm32f429.dtsi wrongly introduced i2s nodes 4, 5 and 6.
Remove them as actually only i2s nodes 2 and 3 are supported on
these socs.

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.
