The current sun50i-h6-pine-h64 DT does not specify which model (A or B)
it supports.
When this file was created, only modelA was existing, but now both model
exists and with the time, this DT drifted to support the model B since it is
the most common one.
Furtheremore, some part of the model A does not work with it like ethernet and
HDMI connector (as confirmed by Jernej on IRC).
So it is time to settle the issue, and the easiest way was to state that
this DT is for model B.
Easiest since only a small name changes is required.
Doing the opposite (stating this file is for model A) will add changes (for
ethernet and HDMI) and so, will break too many setup.
But as asked by the maintainer this patch state this file is for model A.
In the process this patch adds the missing compoments to made it work on
model A.

ath10k
* significant improvements on receive throughput and firmware download
with SDIO bus
* report signal strength for each chain also on SDIO
* set max mtu to 1500 on SDIO devices
If an ocxl device is unbound through sysfs at the same time its AFU is
being opened by a user process, the open code may dereference freed
stuctures, which can lead to kernel oops messages. You'd have to hit a
tiny time window, but it's possible. It's fairly easy to test by
making the time window bigger artificially.
Fix it with a combination of 2 changes:
- when an AFU device is found in the IDR by looking for the device
minor number, we should hold a reference on the device until after
the context is allocated. A reference on the AFU structure is kept
when the context is allocated, so we can release the reference on
the device after the context allocation.
- with the fix above, there's still another even tinier window,
between the time the AFU device is found in the IDR and the
reference on the device is taken. We can fix this one by removing
the IDR entry earlier, when the device setup is removed, instead
of waiting for the 'release' device callback. With proper locking
around the IDR.

- Untangle the somewhat incestous way of how VMALLOC_START is used all across the
kernel, but is, on x86, defined deep inside one of the lowest level page table headers.
It doesn't help that vmalloc.h only includes a single asm header:
#include <asm/page.h> /* pgprot_t */
So there was no existing cross-arch way to decouple address layout
definitions from page.h details. I used this:
#ifndef VMALLOC_START
# include <asm/vmalloc.h>
#endif
This way every architecture that wants to simplify page.h can do so.
- Also on x86 we had a couple of LDT related inline functions that used
the late-stage address space layout positions - but these could be
uninlined without real trouble - the end result is cleaner this way as
well.
