rtc: hym8563: fix incorrect maximum clock rate handling
[ Upstream commit d0a518eb0a692a2ab8357e844970660c5ea37720 ]
When hym8563_clkout_round_rate() is called with a requested rate higher
than the highest supported rate, it currently returns 0, which disables
the clock. According to the clk API, round_rate() should instead return
the highest supported rate. Update the function to return the maximum
supported rate in this case.
