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 285/454] Reduce log spam when mailbox call not implemented
This changes the logging message when a mailbox call
fails to the dev_dbg level. In addition, it fixes the
low voltage detection logging code so that if the
mailbox call doies fails, it logs at error level
and flags so the call is no longer attempted.
