Anbernic RG353M is hardware compatible with RG353P. Only the form-factor
differs. So only one DTS is created for both machines with
"Anbernic RG353P" as default model. If a RG353M is detected, the model
should be overwritten with the correct name.
Actually, it's overwritten with "Anbernic" only making the process of
machine detection a little harder.
However, to determine the size of the string "Anbernic RG353M", it is
sizeof() which is used resulting in obtaining the size of the pointer
(which is 8 bytes on ARM64) not the size of the pointed string.
strlen() should be used instead.

Some of the Powkiddy devices switched to using a different vendor for
the vdd_cpu regulator. Unfortunately the device does not have a new
revision to denote this, so users have no way of knowing in advance.

Add code to detect if a device is present at addresses 0x1c or 0x40 on
the i2c0 bus and update the devicetree if needed.

Refactor the board detection logic (again) to make it compatible with
the upstream device-trees, and switch to OF_UPSTREAM.

Now the device boots with the device-tree for the 353P, and then
loads the correct device tree (of 10) in the later stages of SPL.

This reverts commit 41a60d0e5cef54a59596a58940fa7c9cf071034b.

On some of the supported devices the adc detect code always returns
that the button has been pushed, and as a result the device will
not boot normally.

- Migrate to use IO-domain driver for all boards;
- Use common bss and stack addresses for rk33xx and rk35xx boards;
- Other updates for driver, config and dts;

Add ADC button detect for early SPL stage for RGxx3 device. This is
important because on at least the RG353P and RG353V a clk pin is not
exposed that would allow us to take the eMMC out of the boot path.

Add support to the RGxx3 device for the Powkiddy RGB10MAX3. This device
is extremely similar to all the other devices and can use the same
bootloader with the same detection logic.

While there are currently uses for a stanza of "config BOARD_SPECIFIC_OPTIONS"
followed by "def_bool y" and a series of select/imply statements, having
this option set followed by nothing else doesn't provide anything.
Remove these stanzas.

Add support for the Anbernic RG-ARC-D, Anbernic RG-ARC-S, Powkiddy
RK2023, and Powkiddy RGB30 to the Anbernic RGxx3. While the Powkiddy
devices are manufactured by Powkiddy instead of Anbernic,
the hardware is so similar they can all use the same bootloader.
