[PATCH] ARM: dts: hummingboard: add sgtl5000 support for Hummingboard Pro

[Russell King]

Add the DT description for the SGTL5000 found on the Hummingboard Pro
model.

Signed-off-by: Russell King <rmk+kernel-lFZ/pmaqli7XmaaqVzeoHQ@public.gmane.org>
---
Now that a fix for the SGTL5000 power problems has been merged, this can
be queued for the next merge window.

Macro IMX6QDL_CLK_CKO in include/dt-bindings/clock/imx6qdl-clock.h
