cppcheck cleanup: fix nullPointer errors
There are a number of places where U-Boot intentionally and legally
accesses physical address 0x0000, for example when installing
exception vectors on systems where these are located in low memory.
Add "cppcheck-suppress nullPointer" comments to silence cppcheck
where this is intentional and legal.
