rtc: pcf85063: fix incorrect maximum clock rate handling
[ Upstream commit 186ae1869880e58bb3f142d222abdb35ecb4df0f ]
When pcf85063_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.
