kernel panic when booting on exynos 5440

[Ming Lei]

Hi Pankaj,

In your commit fce9e5bb2(ARM: EXYNOS: Add support for
mapping PMU base address via DT), 'pmu_base_addr' is
only parsed for very limited machines from the table of
'exynos_dt_pmu_match'.  For other boards, 'pmu_base_addr'
will keep its default value of null, then panic() is triggered.

What do you think about the problem?

Thanks,
Ming Lei
