[ 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.
