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.
