ACPI / documentation: Use recommended name in GPIO property names 



The recommended property name for all kinds of GPIOs is to end it with
"-gpios" even if there is only one GPIO. Update the documentation to follow
this fact.

active low or high, the "active_low" argument can be used here.  Setting

it to 1 marks the GPIO as active low.



In our Bluetooth example the "reset-gpio" refers to the second GpioIo()

In our Bluetooth example the "reset-gpios" refers to the second GpioIo()

resource, second pin in that resource with the GPIO number of 31.
