[PATCH v4 5/7] riscv: dts: thead: Add TH1520 mmc controllers and sdhci clock

[Drew Fustini]

Add node for the SDHCI fixed clock. Add mmc0 node for the first mmc
controller instance which is typically connected to the eMMC device.
Add mmc1 node for the second mmc controller instance which is typically
connected to microSD slot.
