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. Signed-off-by: Wolfgang Denk <wd@denx.de>
