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.

Changes in V7:
Add back bus1 pin, which was removed during rebase in v6
as rightly pointed out by Javier[1].
Changes in V6:
Rebased on kukjin's for-next branch[0]
(commit: 77105c8 Merge branch 'v4.0-samsung-fixes-2' into for-next)
