GXL and newer SoC's uses the DMA engine (not blkmv) for crypto HW. Crypto HW doesn't actually use the blkmv clk. At RTL level, crypto engine is hard-wired to a clk81 (CLKID_CLK81). Drop clock-names field from schema: name "blkmv" is invalid and "clk81" is confusing and sounds like something global. Also, GXL crypto IP isn't connected to the second interrupt line. This binding is useless, there are no users of this line. We must remove it from dt-bindings.
