[PATCH] clk: mvebu: flag the crypto clk as CLK_IGNORE_UNUSED

[PATCH] clk: mvebu: flag the crypto clk as CLK_IGNORE_UNUSED

[Boris Brezillon]

Fixes: 29e623475c50267ee3aaa49ebb6cbe107bce8d2a ("clk: mvebu: add
missing CESA gate clk").
The crypto SRAM, used by the armada 370 cpuidle code to workaround a bug
in the BootROM code, requires the crypto clk to be up and running.
Flag the the crypto clk as IGNORE_UNUSED until we add the proper
infrastructure to define the crypto SRAM in the DT and reference the crypto
clk in this SRAM node.

Doesn't compile.  Needs trailing ','

With that fixed, I tested this on top of next-20150615 where mirabox was
previously broken and I confirm it's now working.
