read_current_timer() cleanups
- All implementations can be __devinit
- The function prototypes were in asm/timex.h but they all must be the same,
so create a single declaration in linux/timex.h.
- uninline the sparc64 version to match the other architectures
- Don't bother #defining ARCH_HAS_READ_CURRENT_TIMER to a particular value.
