For Exynos4 platform, L2 cache initialization is done only if

L2 cache initialization path is different when a board boots with
secure firmware. Since there are many Exynos4 based SoCs that boot
in secure mode, enabling this only for boards that don't boot with
secure firmware.

Tested on Exynos4210-Origen board.

Looks good. Unfortunately this is still going to break secure firmware enabled boards, because l2x0_of_init() does not check if the node is enabled.

Best regards,
