Enable WiFi on HP EliteBook 8560w (GPIO config)

angel pons said how to fix it. more info in the patch.

works perfectly. i still see that scancode in dmesg and i guess
i have to assign it to some function that sets software rfkill

hw rfkill is no longer set. it's unblocked, and i can use wifi.

just in time for the libreboot release.

+Subject: [PATCH 1/1] hp/8560w: turn on wifi
+
+according to angel pons, this gpio is WLAN_TRN_OFF#
+and setting it high will make wifi work. testing with
+this change as suggested by angel. see:
+
+https://review.coreboot.org/c/coreboot/+/39398/4/src/mainboard/hp/snb_ivb_laptops/variants/8560w/gpio.c#158
+
+if it makes it into a libreboot release, you can assume
+the fix works. right now we have this problem:
+
+https://codeberg.org/libreboot/lbmk/issues/201
+
+Riku reported:
+
+[  333.890080] atkbd serio0: Unknown key pressed (translated set 2, code 0xf8 on isa0060/serio0).
+[  333.890102] atkbd serio0: Use 'setkeycodes e078 <keycode>' to make it known.
+[  334.104069] atkbd serio0: Unknown key released (translated set 2, code 0xf8 on isa0060/serio0).
+[  334.104090] atkbd serio0: Use 'setkeycodes e078 <keycode>' to make it known.
+
+The wifi stays to hardblocked in rfkill. When the wireless button
+is pressed, nothing changes except for these lines in dmesg.
