ARM: tegra: add non-removable and keep-power-in-suspend property for MMC

This patch adds "non-removable" property of MMC host where the eMMC device
is for Tegra platform.

And the "keep-power-in-suspend" property was used for the SDIO device that
need this to go into suspend mode (e.g. BRCM43xx series).
