ARM: dts: allwinner: a10: Fix PMU interrupt
The Performance Monitoring Unit of the Cortex-A8 cores in the Allwinner
A10 SoC is connected to interrupt line 66, not 3. This is shown in the
manual (where interrupt 3 is assigned to UART2, also in our .dtsi), but
has also been confirmed by triggering an PMU overflow interrupt and
inspecting the IRQ controller status registers (from U-Boot).
Please note that "perf stat" does not use interrupts, this might explain
why this evaded the initial testing.
