[PATCH] clk: mvebu: add missing CESA gate clk

[Boris Brezillon]

Even if not documented in the datasheet, the Armada 370 SoC can actually
gate the CESA (crypto engine) clock.
Add an entry in the gating_desc table to be able to reference the CESA
gateclk in the crypto node.

Thanks for your patch,

but could you also update the documentation ?
