The R329 and D1 SoCs each contain an LRADC with a programming interface compatible to earlier LRADCs. However, the LRADC now has its own clock gate and reset line, instead of being always active. To support this, add clock/reset properties to the binding, and require them for the variant in the new SoCs.
