Fix rpi-eeprom-update when using busybox find

Browse Source 
The busybox implementation of find does not detect recursive nested
symlinks, this results in it finding multiple instances of of_node
matching -samefile, the result of which then fails the -e path test.

The of_node symlink we're tyring to find should match the path
/sys/bus/nvmem/devices/*/of_node so just limit the find depth to 3 as
there's no point searching deeper than that.
