Description

Remove zephyr_cc_option(-Wno-pointer-sign) and fix all code that mixes signed/unsigned pointers.

Contributor guide

Research direction
Search for all instances of signed/unsigned pointer mismatches in the codebase by looking at compiler warnings after removing the Wno pointer sign flag. Fix each occurrence by adjusting pointer types or adding appropriate casts.
