Kumar Gala 6ce4a08c97 drivers: entropy: Get device name from dts if supported
If we have DTS support for an entropy driver we should get the name
generated from DTS ('label' property on the entropy device node).

This is not being used by any drivers, so removing until we need it.

Ulf Magnusson 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.

Ulf Magnusson 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 ...'

Leandro Pereira 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.
