[PATCH 4/6] rtc: r9701: stop setting RWKCNT

[Alexandre Belloni <alexandre.belloni@bootlin.com>]

tm_wday is never checked for validity and it is not read back in
r9701_get_datetime. Avoid setting it to stop tripping static checkers:

        drivers/rtc/rtc-r9701.c:109 r9701_set_datetime()
        error: undefined (user controlled) shift '1 << dt->tm_wday'
