This patch describes the MMC controllers on the Loongson-2K0500/2K1000, with the distinguishing feature being the use of an externally shared APBDMA engine.

This is a skeleton for further development in this patch series. This kernel configuration, CONFIG_MMC_SDHCI_UHS2, will be used in the following commits to indicate UHS-II specific code in sdhci controllers.
