add check infrastructure, default sparse
Add support for running source code checkers on u-boot source, e.g., using sparse to aid with typechecking. This comes in especially handy as SoC vendors mix and match cores and devices with different endianness, thus here we add CHECK_ENDIAN to the otherwise linux kernel default CHECKFLAGS.
