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 677f1e6db9 kconfig: Turn pointless/confusing 'menuconfig's into 'config's
Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.

Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.

    [*] Enable foo ---

This is how it would be shown if there were children but they all
happened to be invisible as well.

With a regular 'config', it turns into

    [*] Enable foo

Change all pointless 'menuconfig's to 'config's.

See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

Jose Alberto Meza e9dd54ed1c drivers: espi: xec: Ensure all eSPI VW are transmitted
When a eSPI slave needs to send back-to-back packets
updating status signal need to guarantee both status
reach the eSPI host, i.e. SCI=0 followed by SCI=1.
This change guarantees both packets are transmitted
over esSPI bus.

Allow to map eSPI host logical UART to a soc UART.

Ulf Magnusson a9490541d6 drivers: espi: kconfig: Remove redundant ESPI_PERIPHERAL_CHANNEL deps.
The ESPI_PERIPHERAL_* symbols are surrounded by an
'if ESPI_PERIPHERAL_CHANNEL' in the same file, so no
need to put 'depends on ESPI_PERIPHERAL' on them.

'if' is just a shorthand for 'depends on'.

Also remove a redundant 'if ESPI' from ESPI_XEC.
drivers/espi/Kconfig.xec is sourced within an 'if ESPI' in
drivers/espi/Kconfig.
