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 257/454] lan78xx: Read LED states from Device Tree
Add support for DT property "microchip,led-modes", a vector of two
cells (u32s) in the range 0-15, each of which sets the mode for one
of the two LEDs. The possible values are:
0=link/activity 1=link1000/activity
2=link100/activity 3=link10/activity
4=link100/1000/activity 5=link10/1000/activity
6=link10/100/activity 14=off 15=on
