rtc: pcf85063: preserve the alarm flag in clkout register updates
The clkout rate and enable/disable helpers update CTRL2 with
regmap_update_bits() but leave the alarm flag (AF) out of the mask. AF is
write-0-to-clear, so an AF that gets asserted between the read and the
write of the read-modify-write is written back as 0 and the pending alarm
interrupt is lost.
Add AF to the mask and write it back as 1 (write-1-to-preserve) so a
concurrently asserted alarm flag survives a clkout reconfiguration.
