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. Compile-tested: bcm2708, bcm2709, bcm2710 (with CONFIG_ALL_KMODS=y) Runtime-tested: bcm2708, bcm2710 Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>

Subject: [PATCH 022/454] Register the clocks early during the boot process, so
that special/critical clocks can get enabled early on in the boot process
avoiding the risk of disabling a clock, pll_divider or pll when a claiming
driver fails to install propperly - maybe it needs to defer.
