Subject: [PATCH 0/3] Add SDHCI support for Canaan K230 SoC

This series is based on the k230 usbphy series[1].

This patch series adds SDHCI support for the Canaan K230 SoC,
which uses Synopsys DWCMSHC SDHCI controllers, include MMC0 and MMC1.
The MMC0 supports eMMC, while MMC1 supports SDIO. Detailed information
can be found in the vendor's manual[2].
