Merge tag 'ib-devres-iio-input-pinctrl-v6.15' into intel/pinctrl

There are a few Intel pin control drivers that are affected
by the devm_kmemdup_array() conversion, merge the ib-devres-iio-input-pinctrl
for making development going smoothly.

* Split devres APIs to a separate header (linux/device/devres.h)
* Move IOMEM_ERR_PTR() to err.h to avoid unneeded loops
* Introduce devm_kmemdup_array()
* Use devm_kmemdup_array() in input, IIO, and pinctrl subsystems
