blinky: "Hello World" Blinky Demo

Demo application that perpetually keeps a LED blinking.

Introduction
The blinky application is one of the most simple applications. It toggles a GPIO pin with a frequency of 2Hz, which has a LED connected to it. A 250ms busy wait is introduced between each toggle, which results in a period of 500ms (2Hz).
LED
The LED's characteristics are defined in the board the blinky application links to, i.e. lib_board_dp.
Additional feature
The main() function has one optional feature. It configures the PIO0_1 pin as CLKOUT, outputting the ARM clock frequency. By hooking a scope to that pin, the ARM clock can be measured.
