Mateusz Jończyk 6e68ee3475 mips: remove redundant macro mc146818_decode_year
The mc146818_decode_year macro is used only in mc146818_get_cmos_time(),
which in turn is called only in
	arch/mips/loongson2ef/common/time.c
and
	arch/mips/mti-malta/malta-time.c
so on mach-jazz it is unused and can be removed. On other platforms it
is defined in the same way, so it can be safely folded into
mc146818_get_cmos_time().
