commit 4bd763568d ("HID: amd_sfh: Support for additional light sensor")
adds additional sensor devices, but forgets to add the number of HID
devices to match. Thus, the number of HID devices does not match the
actual number of sensors.
In order to prevent corruption and system hangs when more than the
allowed number of HID devices are accessed, the number of HID devices is
increased accordingly.

It was reported that commit b300667b33 ("HID: amd_sfh: Disable the
interrupt for all command") had caused increased resume time on HP Envy
x360.
Before this commit 3 sensors were reported, but they were not actually
functional. After this commit the sensors are no longer reported, but
also the resume time increased.
To avoid this problem explicitly look for the number of disabled sensors.
If all the sensors are disabled, clean everything up.

The new driver uses a phys_addr_t to store a DMA address,
which does not work when the two are different size:

Change both the type and the variable name to dma_addr for consistency.

To support AMD Sensor Fusion Hub (SFH) via the HID client's we need to
register the client with the HID framework. Here we mostly address on
how to register the client with the framework and define the interfaces
for communication.
