[PATCH 3/4] arm: exynos4: remove arch_initcall for wakeup interrupt source initialization

[Thomas Abraham]

The of_irq_init function would be setup to invoke the exynos4_init_irq_eint
function when booting using device tree. The arch_initcall for
exynos4_init_irq_eint would duplicate its invocation in that case. Hence,
arch_initcall for exynos4_init_irq_eint is removed and this function is invoked
from the exynos4_init_irq for non-dt case.

Moreover, with single kernel image build, the exynos4_init_irq_eint has no checks
to ensure that it is running on a exynos4 platform. So it would be appropriate
to invoke it from exynos4_init_irq.
