This has two parts:
* intervals_per_second setup
(high speed needs 8000, instead of 1000)
* iso_buffers setup (count of iso buffers depends on
USB speed, 2 is not enough for high speed)

Commit 480b6837aa57 "nvdimm: fix PHYS_PFN/PFN_PHYS mixup" identified
that we were passing an invalid address to devm_nvdimm_ioremap(). With
that fixed it exposed a bug in the memory reservation size for flush
hint tables. Since we map a full page we need to mock a full page of
memory to back the flush hint table entries.

Install the callbacks via the state machine. CPU-hotplug multinstance support
is used with the nocalls() version. Maybe parts of padata_alloc() could be
moved into the online callback so that we could invoke ->startup callback for
instance and drop get_online_cpus().

Install the callbacks via the state machine. It uses the multi instance
infrastructure of the hotplug code to handle each interface.
virtscsi_set_affinity() is removed from virtscsi_init() because
virtscsi_cpu_notif_add() (the function which registers the instance) is invoked
right after it and the cpuhp_state_add_instance() functions invokes the startup
callback on all online CPUs.
The same thing can not be applied virtscsi_cpu_notif_remove() because
virtscsi_remove_vqs() invokes virtscsi_set_affinity() with affinity = false as
argument but the old CPU_DEAD state invoked the function with affinity = true
(which does not match the DEAD callback).

Install the callbacks via the state machine and let the core invoke
the callbacks on the already online CPUs.
Since the online target runs always on the target CPU we can drop
smp_call_function_single(). The functions is invoked with interrupts off to
keep the old calling convention. If the maintainer things that this function
can be called with interrupts enabled then it can be removed :)

The RTL8822BE is a new Realtek wifi and BT device. Support for the BT
part is hereby added.
As this device is similar to most of the other Realtek BT devices, the
changes are minimal. The main difference is that the 8822BE needs a
configuration file for enabling and disabling features. Thus code is
added to select and load this configuration file. Although not needed
at the moment, hooks are added for the other devices that might need
such configuration files.
One additional change is to the routine that tests that the project
ID contained in the firmware matches the hardware. As the project IDs
are not sequential, continuing to use the position in the array as the
expected value of the ID would require adding extra unused entries in
the table, and any subsequant rearrangment of the array would break the
code. To fix these problems, the array elements now contain both the
hardware ID and the expected value for the project ID.

it can be already set when calling smp_register(). This resulted in
