x86/acpi_device: Add support for GPIO output polarity

Instead of hard-coding the polarity of the GPIO to active high/low,
accept it as a parameter in devicetree. This polarity can then be used
while calling into acpi_dp_add_gpio to determine the active low status
correctly.

BUG=chrome-os-partner:55988
BRANCH=None
TEST=Verified that correct polarity is set for reset-gpio on reef.
