revert "rtc: recycle id when unloading a rtc driver"
Revert commit 2830a6d20139df2198d63235df7957712adb28e5. We already perform the ida_simple_remove() in rtc_device_release(), which is an appropriate place. Commit 2830a6d20 ("rtc: recycle id when unloading a rtc driver") caused the kernel to emit ida_remove called for id=0 which is not allocated. warnings when rtc_device_release() tries to release an alread-released ID. Let's restore things to their previous state and then work out why Vincent's kernel wasn't calling rtc_device_release() - presumably a bug in a specific sub-driver.
