drivers/rtc/rtc-isl12022.c: Remove rtc8564 from isl12022_id

rtc8564 appears in i2c_device_id table of both rtc-isl12022.c and
rtc-pcf8563.c.  Commit 8ea9212cbd65 "rtc-pcf8563: add chip id" added the
rtc8564 chip entry to pcf8563.  isl12022 driver is modified from pcf8563
driver, so this looks like a copy-paste bug.
