So what you do with "x86_platform.legacy.rtc" is to skip
add_rtc_cmos(). For ce4100 I added of_have_populated_dt() to skip the
probe.
If you plan to add this to CE4100 you could remove the
"of_have_populated_dt()". It was meant to skip the RTC probe on all OF
platforms but as of now, CE4100 is the only.
