Marek Szyprowski 47f28b41df ARM: dts: exynos: Fix imprecise abort on Mali GPU probe on Exynos4210 
The PMU module of Mali400 GPU is optional and it looks that it is not
present on Exynos4210, because any access to its registers causes external
abort. This patch removes "pmu" interrupt for Exynos4210 SoCs, so the
driver will skip the PMU module. This fixes following fault during kernel
boot:

    Unhandled fault: imprecise external abort (0x1406) at 0x00000000

    (kernel_init) from [<c01010b4>] (ret_from_fork+0x14/0x20)

The PMU module seems to work fine on Exynos4412 SoCs, so the patch also
moves the interrupt definitions to exynos4210.dtsi and exynos4412.dtsi
respectively, to keep only the common part in exynos4.dtsi.
