[PATCH -next] powerpc: kernel/time.c - cleanup warnings

[He Ying]

We found these warnings in arch/powerpc/kernel/time.c as follows:
warning: symbol 'decrementer_max' was not declared. Should it be static?
warning: symbol 'rtc_lock' was not declared. Should it be static?
warning: symbol 'dtl_consumer' was not declared. Should it be static?

Declare 'decrementer_max' in arch/powerpc/include/asm/time.h. And include
proper header in which 'rtc_lock' is declared. Move 'dtl_consumer'
definition behind "include <asm/dtl.h>" because 'dtl_consumer' is declared
there.
