[PATCH 2/4] rtc: ds1302: fix write value for day of week register

[Akinobu Mita <akinobu.mita-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

The valid range of day of week register for DS1302 is 1 to 7.  But the
set_time callback for rtc-ds1302 attempts to write the value of
tm->tm_wday which is in the range 0 to 6.  While the get_time callback
correctly decodes the register.
