[PATCH] gpiolib: acpi: Add quirk for Dell Precision 7780

[Askar Safin]

Dell Precision 7780 often wakes up on its own from suspend. Sometimes
wake up happens immediately (i. e. within 7 seconds), sometimes it happens
after, say, 30 minutes.

Fixes: 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
