Subject: [PATCH v1 2/3] mips: dts: ingenic: Remove unnecessary AIC clocks

These clocks arguably don't belong in the DT because there isn't
much the AIC can do with them in principle. It's safe to remove
them because the jz4740-i2s Linux driver has never depended on
them in the DT, despite superficial appearances to the contrary.
