samples: gpio: add board overlay for up_squared

Browse source 
This adds a board overlay for up_squared to be used with
the GPIO sample. Using the overlay is because the pins
being used are not actually LED and switch but GPIO pins
used as such.

* This uses pin 40 on HAT as LED, and pin 38 as interrupt line.

* Note:
* Need to change the BIOS settings:
* () Advanced -> HAT Configurations:
* - HD-Audio / I2S6 Selec -> Disabled
*
* - GPIO 27 (Pin38) Confi -> Input
* - GPIO 28 (Pin40) Confi -> Output
