Exynos5800: Introduce new proid for Exynos5800

This patch intends to add a new proid for Exynos5800 which is a
variant of Exynos5420. Product id for Exynos5800 is 0x5422.
Both Exynos5420 and Exynos5800 are pin to pin compitable. This
gives us an advantage of reusing Exynos5420 clock, pinmux, memory
and other settings.
