99cca4672c drivers: sam: entropy: implement get_entropy_isr
The commit contributes the implementation of
get_entropy_isr API function for the SAM entropy
driver. The implementation is similar to get_entropy,
with the difference that it does not invoke k_yield()
when called with the ENTROPY_BUSYWAIT options flag set.
When the function is invoked without the ENTROPY_BUSYWAIT
flag, it simply returns whatever data is available,
without busy waiting on the RNG herdware.

969f8f1c68 cleanup: include/: move entropy.h to drivers/entropy.h
move entropy.h to drivers/entropy.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.

Related to #16539

75f77db432 include: misc: util.h: Rename min/max to MIN/MAX
There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.

This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.

All files that use these macros have been updated.
