Input: axp20x-pek - do not register input device on some systems

On some systems (Intel tablets with axp288 pmic) the powerbutton is
also connected to a gpio pin of the SoC, advertised through the
"INTCFD9" / "PNP0C40" acpi device. This leads to double reporting
of powerbutton events, which is undesirable, so one driver needs
to not report input events in this case.

Since the soc_button_array driver for the "PNP0C40" acpi device
also handles wake from suspend on these tablets and since the
axp20x-pel driver requires relative expensive i2c accrsses,
it is best for the axp20x-pek driver to not register an input device
in this case.

Note that this commit leaves the axp20x-driver bound to the
device, rather then returning -ENODEV, this is done so that the
sysfs attributes it offers are kept around.
