ASoC: dt-bindings: samsung,odroid: drop stale clocks

Clocks property was present only to allow usage of assigned-clocks in
the sound card node, however in upstream DTS the assigned-clocks were
moved in commit 4afb06afd768 ("ARM: dts: exynos: move assigned-clock*
properties to i2s0 node in Odroid XU4") to respective I2S nodes. Linux
drivers never parsed "clocks" so it can be safely dropped.
