Christian Helmuth 54cf1334e1 Permit shared access to Intel PCH GPIO device ...

The ported i2c_hid driver contains driver code for the "Intel
Tigerlake/Alderlake PCH pinctrl/GPIO" device. Unfortunately, acpica
driver also accesses the same device on Lid open/close via ACPI AML code
of the DSDT table to read out the state of a GPIO pin connected to the
notebook lid. This would fail as I/O memory is handed out only once and
cannot be shared. The workaround disables the region check for the
specified GPIO I/O memory regions and provides both drivers shared
access to the regions.

This is a preliminary workaround. A general solution should separate the
GPIO driver into a component (e.g., platform driver) that regulates
accesses by i2c_hid and acpica.
