For convenience this also adds a small visionfive_defconfig and the
firmware needed for the brcmfmac driver along with the signed regulatory
database.
The firmware is from the linux-firmware repo and the regulatory database
from the wireless-regdb Fedora package.

When creating dumb buffers with 32bpp and 24bit colour depth this is
default mode return by drm_mode_legacy_fb_format. So we need to support
this for common dumb buffers to just work.

The first DMAC instance in the StarFive JH7100 SoC supports 16 DMA
channels.
FIXME Given there are more changes to the driver than just increasing
DMAC_MAX_CHANNELS, we probably need a new compatible value, too.

This adds support for the StarFive JH7100 and JH7110 SoCs which also
feature this SiFive cache controller.
Unfortunately the interrupt for uncorrected data is broken on the JH7100
and fires continuously, so add a quirk to not register a handler for it.

This adds a compatible for the high speed UARTs on the StarFive JH7100
RISC-V SoC. Just like the regular uarts we also need to keep the input
clocks at their default rate and rely only on the divisor in the UART.

Current u-boot doesn't seem to take into account that some GPIOs are
configured as inputs/outputs of certain peripherals on power-up. This
means it ends up configuring some GPIOs as inputs to more than one
peripheral which the documentation explicitly says is illegal. Similarly
it also ends up configuring more than one GPIO as output of the same
peripheral. While not explicitly mentioned by the documentation this
also seems like a bad idea.
The easiest way to remedy this mess is to just disconnect all GPIOs from
peripherals and have our pinmux configuration set everything up
properly. This, however, means that we'd disconnect the serial console
from its pins for a while, so add a device tree property to keep
certain GPIOs from being reset.

The audio resets are almost identical to the system resets, there are
just fewer of them. So factor out and export a generic probe function,
so most of the reset controller implementation can be shared.

The driver currently uses 64bit I/O on the 32bit registers. This works
because there are 4 assert registers and 4 status register, so they're
only ever accessed on 64bit boundaries.
There are however other reset controllers for audio and video on the SoC
with only one status register that isn't 64bit aligned so 64bit I/O
would result in an unaligned access exception.
Switch to 32bit I/O in preparation for supporting these resets too.

To improve human readability and enable automatic validation, the tuples
in the various properties containing interrupt specifiers should be
grouped.
Fix this by grouping the tuples of "interrupts-extended" properties
using angle brackets.

The generic memset is defined as a byte at time write. This is always
safe, but it's slower than a 4 byte or even 8 byte write.
Write a generic memset which fills the data one byte at time until the
destination is aligned, then fills using the largest size allowed,
and finally fills the remaining data one byte at time.

When the destination buffer is before the source one, or when the
buffers doesn't overlap, it's safe to use memcpy() instead, which is
optimized to use a bigger data size possible.
