Pull x86 platform drivers fixes from Ilpo Järvinen:
"Mostly a few lines fixed here and there except amd/isp4 which improves
swnodes relationships but that is a new driver not in any stable
kernels yet. The think-lmi driver changes also look relatively large
but there are just many fixes to it.
The i2c/piix4 change is a effectively a revert of the commit
7e173eb82a ("i2c: piix4: Make CONFIG_I2C_PIIX4 dependent on
CONFIG_X86") but that required moving the header out from arch/x86
under include/linux/platform_data/
Summary:
- amd/isp4: Improve swnode graph (new driver exception)
- asus-nb-wmi: Use duo keyboard quirk for Zenbook Duo UX8406CA
- dell-lis3lv02d: Add Latitude 5500 accelerometer address
- dell-wmi-sysman: Fix WMI data block retrieval and class dev unreg
- hp-bioscfg: Fix class device unregistration
- i2c: piix4: Re-enable on non-x86 + move FCH header under platform_data/
- intel/hid: Wildcat Lake support
- mellanox:
- mlxbf-pmc: Fix duplicate event ID
- mlxbf-tmfifo: Fix vring_desc.len assignment
- mlxreg-lc: Fix bit-not-set logic check
- nvsw-sn2201: Fix bus number in error message & spelling errors
- portwell-ec: Move watchdog device under correct platform hierarchy
- think-lmi: Error handling fixes (sysfs, kset, kobject, class dev unreg)
- thinkpad_acpi: Handle HKEY 0x1402 event (2025 Thinkpads)
- wmi: Fix WMI event enablement"

Existing swnode graph format is specific to sensor device
and is causing conflicts when accessing standard property
variables outside the sensor driver.
To address this issue, enhanced swnode graph format with
dedicated nodes for i2c and isp devices, with sensor node
added as child to i2c node. This approach allows to have
standard property variables (ex: 'clock-frequency') with
values applicable for each of the devices (sensor, i2c and
isp).
ACPI device driver_data handle is also initialized with root
camera swnode to access the property variables in the graph
in isp and i2c drivers.
