Rework aw_sid so it can work with the nvmem interface. Each SoC expose a set of fuses (for now rootkey/boardid and, if available, the thermal calibration data). A fuse can be private or public, reading private fuse needs to be done via some registers instead of reading directly. Each fuse is exposed as a sysctl. For now leave the possibility for a driver to read any fuse without using the nvmem interface as the awg and emac driver use this to generate a mac address.
