Brian Masney e57edc34bc rtc: nct3018y: fix incorrect maximum clock rate handling 
[ Upstream commit 437c59e4b2 ]

When nct3018y_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.
