HID: i2c-hid: Refactor _DSM helper and add i2c-hid-acpi-prp0001 driver
Move the _DSM call that gets the HID descriptor address from
i2c-hid-acpi.c into i2c-hid-acpi.h as a static inline so both the ACPI
and the new PRP0001 driver can use it. While refactoring, move the
blacklist check and the _DSM call to the top of probe() to avoid a
pointless alloc when the device is blacklisted or does not implement the
_DSM.
Some devices, for example the Lenovo KaiTian N60d and Inspur CP300L3,
are declared with _HID "PRP0001" and _DSD compatible "hid-over-i2c" but
lack "hid-descr-addr" from the _DSD and provide the HID descriptor
address only through an ACPI _DSM. The OF driver fails to probe them
because it requires hid-descr-addr. Add a new driver that handles these
devices by calling the shared _DSM helper.
