mmc: loongson2: Add Loongson-2K SD/SDIO controller driver

Browse source

The MMC controllers on the Loongson-2K series CPUs are similar,
except for the interface characteristics and the use of DMA controllers.

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