rtc: add boot_timesource sysfs attribute
CONFIG_RTC_HCTOSYS allows the kernel to read the system time from the RTC
at boot and resume, avoiding the need for userspace to do so.
Unfortunately userspace currently has no way to know whether this
configuration option is enabled and thus cannot sensibly choose whether to
run hwclock itself or not. Add a hctosys sysfs attribute which indicates
whether a given RTC set the system clock.
