8b6930ebef drivers: entropy: Remove Kconfig HAS_DTS_ENTROPY
Now that all entropy drivers use DTS we can remove HAS_DTS_ENTROPY being
set everywhere as well as Kconfig ENTROPY_NAME since that is now coming
from DT_ENTROPY_NAME.

378d6b137a kconfig: Replace non-defconfig single-symbol 'if's with 'depends on'
Same deal as in commit eddd98f811 ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for the remaining cases outside defconfig
files. See that commit for an explanation.

Will do the defconfigs separately in case there are any complaints
there.

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*/# /'

generated from DTS ('label' property on the entropy device node).

8cf8db3a73 Kconfig: Use a short, consistent style for prompts
Consistently use

    config FOO
            bool/int/hex/string "Prompt text"

instead of

    config FOO
            bool/int/hex/string
            prompt "Prompt text"

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).

The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/
how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.

00ab5ed22a drivers: entropy: Kconfig: Remove redundant 'default n' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.

This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

da9b0ddf5b drivers: Rename random to entropy
This should clear up some of the confusion with random number
generators and drivers that obtain entropy from the hardware.  Also,
many hardware number generators have limited bandwidth, so it's natural
for their output to be only used for seeding a random number generator.
