I wonder if any dedicated "support" for REG_RAM is actually required in pcf85063 driver,
taking into account commit c8ce7ba87d1560babc9f1436035cf2b332f4f603
("misc: Add support for nvmem cells") and the pcf85063 existing support for dm_rtc_read().

I suppose the rest could be specified in the Device Tree?
