This commit adds support for GPIO driver based encoder for SAMv7 boards.
This encoder do not use the microcontroller's dedicated driver but two
GPIO pins with interrupts. The position is calculated based on those
interrupts.
This can be used for boards that do not have pins routed to the dedicated
driver.
