As per the schematic, the extal frequency is 16.6666MHz. However
it is wrongly mentioned as 16666666 on the SoC dtsi.

Given the schematics say the accuracy of the part is specified as 50ppm[*],
changing this doesn't matter much, IMHO.
[*] Yeah, that's more than 4s/day, so it would made a lousy watch, if not
for NTP ;-)
