[patch 084/232] powerpc/85xx: add eSDHC support for MPC8536DS boards

[akpm@linux-foundation.org]

From: Anton Vorontsov <avorontsov@ru.mvista.com>

This patch simply adds sdhci node to the device tree.

We specify clock-frequency manually, so that eSDHC will work without
upgrading U-Boot.  Though, that'll only work for default setup (1500 MHz)
on new board revisions.  For non-default setups, it's recommended to
upgrade U-Boot, since it will fixup clock-frequency automatically.
