Linux expects "unsigned long" has the same bit-width as the pointer, i.e. the size of "unsigned long" is 4 on 32-bit compilers (ILP32) and it is 8 on 64-bit compilers (LLP64). It provides us the convenience in return of the limitation that LP64 data model is not supported.
U-Boot used to follow Linux's way, but it does not now.
Including <stdint.h> means the width of "long" type is provided by the compiler.
Use __SIZEOF_LONG__ instead of hard-coding BITS_PER_LONG.
