powerpc/time: Fix sparse warnings
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 powerpc asm/time.h. Include linux/mc146818rtc.h in powerpc kernel/time.c where 'rtc_lock' is declared. And remove duplicated declaration of 'rtc_lock' in powerpc platforms/chrp/time.c because it has included linux/mc146818rtc.h. Move 'dtl_consumer' definition after "include <asm/dtl.h>" because it is declared there.
