Also remove some duplicated dependencies for the related symbol
ENTROPY_NRF5_RNG.
The redundant ENTROPY_GENERATOR deps. are in files sourced within a
if ENTROPY_GENERATOR
...
endif
block in drivers/entropy/Kconfig.
The redundant ENTROPY_NRF5_RNG deps. are due to redundant 'depends on'
within an 'if' in the same file.
Tip: Jump to symbols with '/' in the menuconfig and press '?' to check
their dependencies. If there are duplicated dependencies, the
'included via ...' path can be handy to discover where they are added.

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 ...'

Instead of every hardware number generator driver providing an
implementation of this function, use the random device API to
centralize the implementation of this function.
This is a very simplistic function that can be seen as a stepping stone
to refactor the random number generation in Zephyr.

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.
