commit 4bd76356 ("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.

Add reset GPIO support to the generic i2c-hid-of driver

This is necessary to make the Wacom digitizer on the Lenovo Yoga Book 1
(yb1-x90f/l) work and this will also allow consolidating the 2 specialized
i2c-hid-of-elan.c and i2c-hid-of-goodix.c drivers into the generic
i2c-hid-of driver.

For now the new "post-reset-deassert-delay-ms" property is only used on
x86/ACPI (non devicetree) devs. IOW it is not used in actual devicetree
files and the same goes for the reset GPIO. The devicetree-bindings
maintainers have requested properties like these to not be added to
the devicetree-bindings, so the new property + GPIO are deliberately
not added to the existing devicetree-bindings.

There are some x86 tablets / 2-in-1s which ship with Android as their
factory OS image. These have pretty broken ACPI tables, relying on
everything being hardcoded in the factory kernel image.

platform/x86/x86-android-tablets.c manually instantiates i2c-clients for
i2c devices on these tablets to make them work with the mainline kernel.

The Lenovo Yoga Book 1 (yb1-x90f/l) is such a 2-in-1. It has 2 I2C-HID
devices its main touchscreen and a Wacom digitizer. Its main touchscreen
can alternatively also be used in HiDeep's native protocol mode but
for the Wacom digitizer we really need I2C-HID.

This patch allows using i2c-hid-of on non OF platforms so that it can
bind to a non ACPI instantiated i2c_client on x86 for the Wacom digitizer.
Note the driver already has an "i2c-over-hid" i2c_device_id (rather then
an of_device_id).

Besides enabling building on non-OF platforms this also replaces
the only of_property_read_u32() call with device_property_read_u32() note
that other properties where already read using device_property_read_...().

 "Several fixes for driver startup regressions that landed during the
  merge window as well as some older bugs.

  The regressions were due to a lack of testing with what the CXL
  specification calls Restricted CXL Host (RCH) topologies compared to
  the testing with Virtual Host (VH) CXL topologies. A VH topology is
  typical PCIe while RCH topologies map CXL endpoints as Root Complex
  Integrated endpoints. The impact is some driver crashes on startup.

  This merge window also added compatibility for range registers (the
  mechanism that CXL 1.1 defined for mapping memory) to treat them like
  HDM decoders (the mechanism that CXL 2.0 defined for mapping
  Host-managed Device Memory). That work collided with the new region
  enumeration code that was tested with CXL 2.0 setups, and fails with
  crashes at startup.

  Lastly, the DOE (Data Object Exchange) implementation for retrieving
  an ACPI-like data table from CXL devices is being reworked for v6.4.
  Several fixes fell out of that work that are suitable for v6.3.

  All of this has been in linux-next for a while, and all reported
  issues [1] have been addressed.

  Summary:

   - Fix several issues with region enumeration in RCH topologies that
     can trigger crashes on driver startup or shutdown.

   - Fix CXL DVSEC range register compatibility versus region
     enumeration that leads to startup crashes

   - Fix CDAT endiannes handling
