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.

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.

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 syscon regmap and offset to the USB mode register is only used at
probe time, so there is no need to store it in the device data. Just get
the regmap pointer in the cdns_mode_init() function where it is needed.
Also this function never uses the platform device, so just pass the
device pointer directly.

Pull tracing fixes from Steven Rostedt:
- Fix buffer overflow in osnoise_cpu_write()
The allocated buffer to read user space did not add a nul terminating
byte after copying from user the string. It then reads the string,
and if user space did not add a nul byte, the read will continue
beyond the string.
Add a nul terminating byte after reading the string.
- Fix missing check for lockdown on tracing
There's a path from kprobe events or uprobe events that can update
the tracing system even if lockdown on tracing is activate. Add a
check in the dynamic event path.
- Add a recursion check for the function graph return path
Now that fprobes can hook to the function graph tracer and call
different code between the entry and the exit, the exit code may now
call functions that are not called in entry. This means that the exit
handler can possibly trigger recursion that is not caught and cause
the system to crash.
Add the same recursion checks in the function exit handler as exists
in the entry handler path.

function_graph_enter_regs() prevents itself from recursion by
ftrace_test_recursion_trylock(), but __ftrace_return_to_handler(),
which is called at the exit, does not prevent such recursion.
Therefore, while it can prevent recursive calls from
fgraph_ops::entryfunc(), it is not able to prevent recursive calls
to fgraph from fgraph_ops::retfunc(), resulting in a recursive loop.
This can lead an unexpected recursion bug reported by Menglong.
is_endbr() is called in __ftrace_return_to_handler -> fprobe_return
-> kprobe_multi_link_exit_handler -> is_endbr.
To fix this issue, acquire ftrace_test_recursion_trylock() in the
__ftrace_return_to_handler() after unwind the shadow stack to mark
this section must prevent recursive call of fgraph inside user-defined
fgraph_ops::retfunc().
This is essentially a fix to commit 4346ba160409 ("fprobe: Rewrite
fprobe on function-graph tracer"), because before that fgraph was
only used from the function graph tracer. Fprobe allowed user to run
any callbacks from fgraph after that commit.

The condition to check if the actions buffer needs to be resized was
incorrect. The check `self->size >= self->len` would evaluate to
true on almost every call to `actions_new()`, causing the buffer to
be reallocated unnecessarily each time an action was added.
Fix the condition to `self->len >= self.size`, ensuring
that the buffer is only resized when it is actually full.
