Core kernel code:

Allow the stats formatting functions to be built in without stdio.h being included inside tasks.c.

Kernel port code:
- Slight change to the Cortex-A GIC-less port to move all non portable code to the application level.

SAMA5D4 demo project:
- Update the Atmel provided library to V1.1.
- Create a DDR build configuration.
- Ensure interrupts are all edge sensitive.
- Update the regtest code to use all 32 flop registers.
