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 279/454] BCM270X_DT: Add sdio_overclock parameter
The Arasan MMC interface is used on some RPis to drive the SDIO
link to the WiFi controller. The downstream bcm2835-mmc driver,
like the bcm2835-sdhost driver, can be over- (or under-) clocked.
Add a common parameter - sdio_overclock - to all DTBs to control it.
