RISC-V: Canaan devicetree fixes
This series should rid us of dtbs_check errors for the RISC-V Canaan k210 based boards. To make keeping it that way a little easier, I changed the Canaan devicetree Makefile so that it would build all of the devicetrees in the directory if SOC_CANAAN.

description:

The Canaan K210 SRAM memory controller is responsible for the system's 8 MiB
11+
of SRAM. The controller is initialised by the bootloader, which configures
12+
its clocks, before OS bringup.
