rtc: pcf8563: fix output clock rate
[ Upstream commit a3350f9c57ffad569c40f7320b89da1f3061c5bb ]
The pcf8563_clkout_recalc_rate function erroneously ignores the
frequency index read from the CLKO register and always returns
32768 Hz.
Fixes: a39a6405d5f9 ("rtc: pcf8563: add CLKOUT to common clock framework")
