Subject: [PATCH v2 1/2] rtc: wilco-ec: Remove yday and wday calculations

The tm_yday and tm_wday fields are not used by userspace,
so since they aren't needed within the driver, don't
bother calculating them. This is especially needed since
the rtc_year_days() call was crashing if the HW returned
an invalid time.
