Subject: [PATCH v11 16/22] dt-bindings: crypto: amlogic,gxl-crypto: correct clk and interrupt lines

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.

Fixes: 7f7d115dfb51 ("dt-bindings: crypto: Add DT bindings documentation for amlogic-crypto")
