riscv: dts: canaan: fix the k210's memory node

The k210 U-Boot port has been using the clocks defined in the
devicetree to bring up the board's SRAM, but this violates the
dt-schema. As such, move the clocks to a dedicated node with
the same compatible string. The regs property does not fit in
either node, so is replaced by comments.
