[PATCH] ppc32: Fixup <asm/time.h> includes

include/asm-ppc/time.h has a slightly odd include list which means that
some files include <asm/time.h> and also hope to get others that they
really shouldn't be.  This makes <asm/time.h> use <linux/types.h> (time_t)
and <linux/rtc.h> (struct rtc_time) instead of <linux/mc16818rtc.h>, and
fixes up the fallout from the change.

Compile-tested on lite5200, walnut and defconfig, along with by-hand'ing
everything else that included <asm/time.h>.
