Subject: [PATCH 4/4] ARM: STi: DT: STiH407: Add dt nodes for sdhci and emmc.

The nodes have been split to allow as much commonality as possible.
The stih407 has a silicon bug with eMMC UHS modes (with top regs)
and as such doesn't have any of the uhs dt properties.

Signed-off-by: Peter Griffin <peter.griffin@...aro.org>
