Catalin Visinescu 081e4c478a drivers/: Multiple Drivers Are Registered With World Writable - Part 2 
Permissions (Part 2)

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.

DISCLAIMER: I tried to be strict with the settings, better to relax them
later if it's needed.

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

See https://github.com/apache/nuttx/issues/19410

Compiles ok.
