hwmon: (aquacomputer_d5next) Add support for Aquacomputer High Flow USB and 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.

hwmon: (aquacomputer_d5next) Add support for Aquacomputer Leakshield

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.

hwmon: (aquacomputer_d5next) Add fan PWM control for Aquaero

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.

hwmon: add driver for Aquacomputer D5 Next

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.
