Subject: [PATCH] ARM: realview: remove eb-mp clcd IRQ

We get a dtc warning about the CLCD interrupt being invalid:

arch/arm/boot/dts/arm-realview-eb-11mp-ctrevb.dtb: Warning (interrupts_property): interrupts size is (8), expected multiple of 12 in /fpga/charlcd@...08000

According to the datasheet I found and the old board file, this
line is not connected, so I'm removing the respective properties here.
