PATCH 1/1 ARM: exynos4: use the variable for S5P_VA_SYSRAM

From: Kyungmin Park <[email protected]>

The CPU1_BOOT_REG and S5P_VA_SYSRAM is used mixed for setup secondary_startup. Make it consistent statement for setup.

It's also helpful for EVT0 which has another SYSRAM address handling.

	if (soc_is_exynos4210_evt0())
		sysram = ioremap(EXYNOS4210_EVT0_SYSRAM, SZ_4K);
