Enabling emmc without enabling its controller doesn't do any good.
Enable its controller as well to make it work.

Thanks Guenter. The description in aspeed-g6.dtsi changed at some
point and Tacoma was not updated.

This node is redundant, as it is not disabled in the dtsi.
Andrew, should we add disabled to the emmc node?
Or remove the label completely, and just have emmc_controller?
Cheers,
Joel

Probably. Also the nodes are badly named, partly because of the structure
of the IP block. 'emmc' in this instance isn't the actual card, it's the SDHCI,
and emmc_controller is a 'parent' that contains some global state which
applies to one or more SDHCIs inside the IP block.
We should probably cook up better names.

Maybe this is a better approach? The eMMC IP block only has one associated
SDHCI, so that would make sense.
