Remove the #ifdef check for CONFIG_DEBUG_FS and the empty variant
of aqc_debugfs_init(), because the debugfs functions already do nothing
if debugfs isn't enabled.

MPS Flow
Extend aquacomputer_d5next driver to expose various hardware sensors of the
Aquacomputer High Flow USB flow sensor, which communicates through a
proprietary USB HID protocol. This commit also adds support for the sensors
of the MPS Flow devices, as they have the same USB product ID and sensor
layouts. Implemented by Leonard Anderweit [1].
Internal and external temp sensor readings are available, along with
the flow sensor.
Additionally, serial number and firmware version are exposed through
debugfs.

Add a 200ms delay after sending a ctrl report to Quadro,
Octo, D5 Next and Aquaero to give them enough time to
process the request and save the data to memory. Otherwise,
under heavier userspace loads where multiple sysfs entries
are usually set in quick succession, a new ctrl report could
be requested from the device while it's still processing the
previous one and fail with -EPIPE. The delay is only applied
if two ctrl report operations are near each other in time.
Reported by a user on Github [1] and tested by both of us.

Commit 662d20b3a5af ("hwmon: (aquacomputer_d5next) Add support for
temperature sensor offsets") changed aqc_get_ctrl_val() to return
the value through a parameter instead of through the return value,
but didn't fix up a case that relied on the old behavior. Fix it
to use the proper received value and not the return code.

Extend aquacomputer_d5next driver to expose various hardware sensors of the
Aquacomputer Leakshield leak prevention system, which communicates
through a proprietary USB HID protocol. Implemented by Noah Bergbauer [1].
Two temperature sensors are exposed, along with pressure (current, min, max
and target), reservoir volume (total and filled), pump speed and flow. Pump
speed and flow values are user provided and allow the Leakshield to
optimize its operation. Writing them to the device is subject of future
patches.

Add the option to control fan PWM on Aquacomputer Aquaero. The Aquaero is
the most complex Aquacomputer device, control is therefore more complicated
then on already supported devices.
Setting PWM requires multiple steps. First, an internal static PWM
controller is set to the desired PWM value. Second, the fan is set to use
that PWM controller. Last, the minimum and maximum accepted PWM values
of the fan are set to allow all possible PWM values.

The offsets for setting speeds of fans connected to Quadro are off by one.
Set them to their correct values.
The offsets as shown point to registers for setting the fan control mode,
which will be explored in future patches, but slipped in here. When
setting fan speeds, the resulting values were overlapping, which made the
fans still run in my initial testing.

As preparation for adding support for more devices in upcoming patches,
move device-specific data, such as number of fans, temperature sensors,
register offsets etc. to struct aqc_data. This is made possible by
the fact that the supported Aquacomputer devices share the same layouts
of sensor substructures. This allows aqc_raw_event() and others to stay
general and not be cluttered with similar loops for each device.

This driver exposes hardware sensors of the Aquacomputer D5 Next
watercooling pump, which communicates through a proprietary USB HID
protocol.
Available sensors are pump and fan speed, power, voltage and current, as
well as coolant temperature. Also available through debugfs are the serial
number, firmware version and power-on count.
Attaching a fan is optional and allows it to be controlled using
temperature curves directly from the pump. If it's not connected,
the fan-related sensors will report zeroes.
The pump can be configured either through software or via its physical
interface. Configuring the pump through this driver is not implemented,
as it seems to require sending it a complete configuration. That
includes addressable RGB LEDs, for which there is no standard sysfs
interface. Thus, that task is better suited for userspace tools.
This driver has been tested on x86_64, both in-kernel and as a module.
