From: Seungwon Jeon <tgih.jun@samsung.com>
HS400 timing values are added for SMDK5420, exynos5420-peach-pit
and exynos5800-peach-pi boards.
This also adds RCLK GPIO line, this gpio should be in pull-down
state.
This also enables HS400 on peach-pi and this updates the clock frequency
to 800MHz to be set as input clock to controller.
