ARM: mvebu: move L2 cache initialization in init_early()
In preparation for moving the IRQ controller driver to drivers/irqchip/, we don't want the IRQ controller driver to be responsible for initializing the L2 cache. Instead, let's initialize the L2 cache at the init_early() level, like mach-exynos/common.c is doing.
