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.

the same compatible string. The regs property does not fit in

https://canaan-creative.com/wp-content/uploads/2020/03/kendryte_standalone_programming_guide_20190311144158_en.pdf
Section 15.4.3.3:
SPI0 and SPI1 supports: standard, dual, quad and octal transfers.
SPI3 supports: standard, dual and quad transfers (octal is not supported).
In order to support quad transfers (Quad SPI), SPI3 must have four IO wires
connected to the SPI flash.
Update the device tree to specify the correct bus width.
Tested on maix bit, maix dock and maixduino, which all have the same
SPI flash (gd25lq128d) connected to SPI3. maix go is untested, but it
would not make sense for this k210 board to be designed differently.

Commit 67d96729a9 ("riscv: Update Canaan Kendryte K210 device tree")
incorrectly removed two entries from the PLIC interrupt-controller node's
interrupts-extended property.
The PLIC driver cannot know the mapping between hart contexts and hart ids,
so this information has to be provided by device tree, as specified by the
PLIC device tree binding.
The PLIC driver uses the interrupts-extended property, and initializes the
hart context registers in the exact same order as provided by the
interrupts-extended property.
In other words, if we don't specify the S-mode interrupts, the PLIC driver
will simply initialize the hart0 S-mode hart context with the hart1 M-mode
configuration. It is therefore essential to specify the S-mode IRQs even
though the system itself will only ever be running in M-mode.
Re-add the S-mode interrupts, so that we get working IRQs on hart1 again.

The previous commit fixed up all shell scripts to not include
include/config/auto.conf.
Now that include/config/auto.conf is only included by Makefiles,
we can change it into a more Make-friendly form.
Previously, Kconfig output string values enclosed with double-quotes
(both in the .config and include/config/auto.conf):
CONFIG_X="foo bar"
Unlike shell, Make handles double-quotes (and single-quotes as well)
verbatim. We must rip them off when used.
There are some patterns:
[1] $(patsubst "%",%,$(CONFIG_X))
[2] $(CONFIG_X:"%"=%)
[3] $(subst ",,$(CONFIG_X))
[4] $(shell echo $(CONFIG_X))
These are not only ugly, but also fragile.
[1] and [2] do not work if the value contains spaces, like
CONFIG_X=" foo bar "
[3] does not work correctly if the value contains double-quotes like
CONFIG_X="foo\"bar"
[4] seems to work better, but has a cost of forking a process.
Anyway, quoted strings were always PITA for our Makefiles.
This commit changes Kconfig to stop quoting in include/config/auto.conf.
These are the string type symbols referenced in Makefiles or scripts:

ARC_BUILTIN_DTB_NAME

Update the Canaan Kendryte K210 base device tree k210.dtsi to define
all supported peripherals of the SoC, their clocks and reset lines.
The device tree file k210.dts is renamed to k210_generic.dts and
becomes the default value selection of the configuration option
SOC_CANAAN_K210_DTB_BUILTIN_SOURCE. 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.
