RISC-V: Canaan devicetree fixes

Browse Source 
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.

Ilitek ILI9341 display panels
This binding is for display panels using an Ilitek ILI9341 controller in SPI
mode.
Required properties:
- compatible: "adafruit,yx240qv29", "ilitek,ili9341"
- dc-gpios: D/C pin
- reset-gpios: Reset pin
The node for this driver must be a child node of a SPI controller, hence
all mandatory properties described in ../spi/spi-bus.txt must be specified.
Optional properties:
- rotation: panel rotation in degrees counter clockwise (0,90,180,270)
- backlight: phandle of the backlight device attached to the panel
Example:
display@0{
compatible = "adafruit,yx240qv29", "ilitek,ili9341";
reg = <0>;
spi-max-frequency = <32000000>;
dc-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>;
reset-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;
rotation = <270>;
backlight = <&backlight>;
};

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