drivers/efuse/efuse: Drivers Registered With World Write Permissions(Part 1)

Browse source 
Description:

In kernel builds, any unprivileged process running on the NuttX device
can open /dev/efuse and attempt to read/write fuse content. Reading the
fuses may provide valuable information to an attacker controlling the user
process. The write operation, in extreme cases where the fuse blocks are
not locked, may brick the device.

This is part of https://github.com/apache/nuttx/issues/19410

Compiles ok.
