Both operands of an operator in the arithmetic conversions
performed shall have the same essential type category.

Changes are related to converting the integer constants to the
unsigned integer constants

6216c6cf5b random: Add syscalls for random subsystem
Create syscalls to make possible using random APIs from user mode
threads. These APIs can have different implementations, like using
entropy driver or Xoroshiro128. Some of these implementations also have
some globals to preserve state between calls.

Make it run entire in user space would require user adding these globals
to their memeory domains and/or grant access to entropy device. Syscalls
simplify its usage.

076eee3abc subsys/random: fix unused value warning
When using LLVM/Clang, it complains about memcpy() being
casted to (void *):

  warning: expression result unused; should this cast be to 'void'? [-Wunused-value]

So change those to (void) instead as the return of memcpy()
is not used anyway.

afdc63f320 subsys/random: Add cryptographically secure and bulk fill functions
1) Add cryptographically secure random functions to provide
FIPS 140-2 compliant random functions.

2) Add name to random function choice selectors to ease
selection in SOC .defconfig files

3) Add bulk fill random functions.

e1e05a2eac cleanup: include/: move atomic.h to sys/atomic.h
move atomic.h to sys/atomic.h and
create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

adce1d1888 subsys: Add random subsystem
Some "random" drivers are not drivers at all: they just implement the
function `sys_rand32_get()`.  Move those to a random subsystem in
preparation for a reorganization.
