Ack, looking at configs, the main/platform RTC driver is builtin on
supported platforms. Perhaps we should have something on the enforcer
(rtc-cmos enforced on x86, this on highbank, RTC_DRV_TWL4030 on

Also, as already noted, because of the config shuffle modules.ignore
or ignore.modules is needed to be added.
