[PATCH v2] powerpc/85xx: Add eSDHC support for MPC8536DS boards

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.

Can you update the mpc8536ds_36b.dts as well (its in my next branch)

Sure thing.
