Since we have to provide the clock very early on, the RTC driver cannot be built as a module. Make sure that won't happen.

I might have gotten this wrong in the past. It seems that the .remove callback can still be called, even if the driver is builtin, by unbinding the driver from the device using the sysfs interface. So we still need it regardless. We can get rid of the .remove callback by switching to devm_rtc_device_register, but that is a separate issue. Also, a personal preference, is that this change should precede the clk change you mentioned in the commit message, since you are making this change in anticipation of possible breakage by that one. Regards ChenYu
