Ulf Magnusson bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

    git ls-files '*Kconfig*' | \
        xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

Ulf Magnusson 70da85c8ec kconfig: drivers: i2s: Remove redundant deps.
I2S_STM32 is already within an 'if I2S', in drivers/i2s/Kconfig.

'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an
if condition could include (directly or indirectly) forward references
to symbols not defined yet.

Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

Ulf Magnusson 9aab5cef96 kconfig: Remove redundant 'default n' properties
Some more were added since the cleanup pass in June 2018. See e.g.
commit 2d50da70a1 ("drivers: ipm: Kconfig: Remove redundant 'default n'
properties") for a motivation. It also avoids people wondering whether
or not they need to put in 'default n'.

Armando Visconti 7b82e9f2d0 drivers: i2s: Add support for I2S stm32
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).
