Clang 15 added a new warning type `-Wdeprecated-non-prototype` that warns about the functions without prototypes, which have been deprecated since the C89 and will not work in the upcoming C2x. This commit disables the warning because Zephyr deliberately makes use of the functions without prototypes to allow the use of a "generic" function pointer (notoriously in the cbprintf implementation) and Zephyr will not move to the C2x in the foreseeable future.

@galak Since you requested this backport, could you provide some rationale on why this is necessary? |

The first commit is needed for arm-clang to build w/o everything causing warnings. I just tagged the original PR and thus is backported all the commits from it. |

There was a problem hiding this comment.
No problem with this since the Zephyr SDK version has not changed as part of this update, and the update to Clang 15 does not introduce any breaking changes.

DNM until the node image is updated to cache the CI image v0.24.3. |
