dt-bindings: etnaviv: add slave interface clock
Newer GPU cores added a new clock input, which allows to gate the slave (AHB) interface independently from other parts of the GPU. Add it to the supported clocks. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Reviewed-by: Rob Herring <robh@kernel.org>
