The device tree file k210.dts is renamed to k210_generic.dts and becomes the default value selection of the SOC_CANAAN_K210_DTB_BUILTIN_SOURCE configuration option. No device beside the serial console is defined by this device tree. This makes this generic device tree suitable for use with a builtin initramfs with all known K210 based boards. These changes result in the K210_CLK_ACLK clock ID to be unused and removed from the dt-bindings k210-clk.h header file. Most updates to the k210.dtsi file come from Sean Anderson's work on U-Boot support for the K210.
