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 052/454] firmware: bcm2835: Support ARCH_BCM270x
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Support booting without Device Tree.
Turn on USB power.
Load driver early because of lacking support for deferred probing
in many drivers.

firmware: bcm2835: Don't turn on USB power
The raspberrypi-power driver is now used to turn on USB power.
This partly reverts commit:
