Add node for the fixed reference clock used for emmc and sdio nodes.
Add emmc node for the 1st dwcmshc instance which is typically connected
to an eMMC device. Add sdio0 node for the 2nd dwcmshc instance which is
typically connected to microSD slot. Add sdio1 node for the 3rd dwcmshc
instance which is typically connected to an SDIO WiFi module. The node
names are based on Table 1-2 C910/C906 memory map in the TH1520 System
User Manual.

Thanks! The rest of the patches look good too, but I don't really have
a schematic
to do proper review.

Thanks for reviewing. The BeagleV-Ahead board is open source hardware so
there is the full schematic and PCB layout in:
