It turns out that systemd-logind by default listens for KEY_RESTART input
events and reboots the machine, which isn't great - So use KEY_VENDOR for
the vendor specific identify button instead to not conflict.

Barco P50 board
Add a driver providing access to the GPIOs for the identify button and led
present on Barco P50 board, based on the pcengines-apuv2.c driver.
There is unfortunately no suitable ACPI entry for the EC communication
interface, so instead bind to boards with "P50" as their DMI product family
and hard code the I/O port number (0x299).
The driver also hooks up the leds-gpio and gpio-keys-polled drivers to the
GPIOs, so they are finally exposed as:
LED:
/sys/class/leds/identify
Button: (/proc/bus/input/devices)
I: Bus=0019 Vendor=0001 Product=0001 Version=0100
N: Name="identify"
P: Phys=gpio-keys-polled/input0
S: Sysfs=/devices/platform/barco-p50-gpio/gpio-keys-polled/input/input10
U: Uniq=
H: Handlers=event10
B: PROP=0
B: EV=3
B: KEY=1000000 0 0 0 0 0 0
