reset: sunxi: Convert driver private data to platform data

The reason here is the same as the reason for changing the clock driver:
platform data can be provided when binding the driver.

clk: sunxi: Convert driver private data to platform data

All of the driver private data should really be platform data since it
is determined statically (selected by the compatible string or extracted
from the devicetree). Move everything to platform data, so it can be
provided when binding the driver. This is useful for SPL, or for
instantiating the driver as part of an MFD.

clk: sunxi: Use a single driver for all variants

Now that all of the variants use the same bind/probe functions and ops,
there is no need to have a separate driver for each variant. Since most
SoCs contain two variants (the main CCU and PRCM CCU), this saves a bit
of firmware size and RAM.

clk: sunxi: Prevent out-of-bounds gate array access

Because the gate arrays are not given explicit sizes, the arrays are
only as large as the highest-numbered gate described in the driver.
However, only a subset of the CCU clocks are needed by U-Boot. So there
are valid clock specifiers with indexes greater than the size of the
arrays. Referencing any of these clocks causes out-of-bounds access.
Fix this by checking the identifier against the size of the array.

clk: sunxi: Store the array sizes in the CCU descriptor

The reset array size is currently used for bounds checking in the reset
driver. The same bounds check should really be done in the clock driver.

Currently, the array size is provided to the reset driver separately
from the CCU descriptor, which is a bit strange. Let's do this the usual
way, with the array sizes next to the arrays themselves.

Merge branch '2022-07-14-migrate-wiki-to-sphinx'

- Merge the majority of the relevant wiki content to doc/process/ and
convert to Sphinx. Begin cleaning up and modernizing the content as
well to match current process. There is still more work to be done in
this regard.

doc: Add in the historical release statistics found on the wiki

The wiki had gitdm-generated release statistics starting with v1.3.0.
Re-generate this information as Sphinx. This aims to be as historically
accurate as possible and so some company renames were kept to their old
rather than current name until we had made the switch previously.

doc: process: Correct and expand slightly on the Merge Window concept

For quite a long time we've been using a 3 week, rather than 2 week,
merge window as it was only 2 weeks during the timeframe where we did 2
month rather than 3 month releases. This corrects the places that still
had 2 weeks and tries to make things a bit clearer overall.

doc: Add doc/develop/release_cycle.rst

Migrate the RelaseCycle wiki page to Sphinx. In terms of visible
changes, we stop having a dynamic countdown to when the release is. And
we drop the year-based statistics, that were not being kept up to date.
For the moment, we only link to statistics for v2022.07 but will add
back the historical data in a subsequent patch.

process.rst: Modernize the "Workflow of a Custodian" section

The "Workflow of a Custodian" section on the wiki had not been changed
in quite some time to reflect how the process has been functioning for
some time. First, update some links to point to modern and current
sources of information.

Second, and more overarching, reword much of the section. This expands
on the expectations of both custodians and developers when it comes to
rebasing patches. Rework the final points to be clearer that Custodians
are expected to do their best to test the changes and ask for help when
needed, as well as that pull requests are expected in a timely manner.

tools: mtk_image: add support for MT7621 NAND images

The BootROM of MT7621 requires a image header for SPL to record its size
and load address when booting from NAND.

To create such an image, one can use the following command line:
mkimage -T mtk_image -a 0x80200000 -e 0x80200000 -n "mt7621=1"
-d u-boot-spl-ddr.bin u-boot-spl-ddr.img

spl: spl_legacy: fix the use of SPL_COPY_PAYLOAD_ONLY

If the payload is compressed, SPL_COPY_PAYLOAD_ONLY should always be set
since the payload will not be directly read to its load address. The
payload will first be read to a temporary buffer, and then be decompressed
to its load address, without image header.

If the payload is not compressed, and SPL_COPY_PAYLOAD_ONLY is set, image
header should be skipped on loading. Otherwise image header should also be
read to its load address.
