Andrei.Stefanescu@microchip.com fb0b35d307 gpio: add driver for SAMA5D2 PIOBU pins ...

PIOBU pins do not lose their voltage during Backup/Self-refresh.
This patch adds a simple GPIO controller for them and a
maintainer for the driver.

This driver adds support for using the pins as GPIO
offering the possibility to read/set the voltage.
