rtc: rv3028: fix incorrect maximum clock rate handling
[ Upstream commit b574acb3cf7591d2513a9f29f8c2021ad55fb881 ]
When rv3028_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.
