Add missing compatible strings from 4.9/960-add-rasbperrypi-compatible.patch, using upstream names for compute modules. Add extra patch to enable the LEDs on lan78xx.

Subject: [PATCH 308/454] overlays: Add sdtweak features for network booting
It has been observed that a Pi with no SD card will poll the interface
continuously, using up to 10% CPU. Add some new parameters to the
sdtweak overlay to control this behaviour:
poll_once Only look for a card once, at boot time. If none is found
then the interface is effectively disabled.
enable Set to "off" or "no" to completely disable the interface.
See: https://github.com/raspberrypi/linux/issues/2567
