Martin Roth eca844b949 pcengines/apu1: Supply _HID object for ACPI GPIO devices
The _HID was present for the top level BTNS and LEDS Devices, but
was missing in the individual devices.

The alternative would be to supply the GPIO being used as an _ADR
object, but since it looks like the driver already has another
method of handling that, it isn't required.

Fixes these IASL warnings:
dsdt.aml   1522:   Device (BTN1)
Warning  3141 -              ^ Missing dependency
(Device object requires a _HID or _ADR in same scope)
dsdt.aml   1567:   Device (LED1)
Warning  3141 -              ^ Missing dependency
(Device object requires a _HID or _ADR in same scope)
dsdt.aml   1576:   Device (LED2)
Warning  3141 -              ^ Missing dependency
(Device object requires a _HID or _ADR in same scope)
dsdt.aml   1587:   Device (LED3)
Warning  3141 -              ^ Missing dependency
(Device object requires a _HID or _ADR in same scope)
