Subject: [PATCH v2 1/4] m68k: rename UL() to TO_UL()

ARM, ARM64 and UniCore32 define UL(x) like follows:

  #define UL(x) _AC(x, UL)

While, M68K defines it differently:
  #define UL(x) ((unsigned long) (x))

I am moving the former to a common header in the next commit.
Beforehand, this commit renames the latter to avoid name conflict.
