cpu/qn908x: Initial minimal support for NXP QN908x CPUs. The NXP QN908x CPU family is a Cortex-M4F CPU with integrated USB, Bluetooth Low Energy and in some variants NFC. This patch implements the first steps for having support for this CPU. While the QN908x can be considered the successor of similar chips from NXP like the KW41Z when looking at the feature set, the internal architecture, boot image format and CPU peripherals don't match those in the Kinetis line. Therefore, this patch creates a new directory for just the QN908x chip under cpu/qn908x. The minimal set of peripherals are implemented in this patch to allow the device to boot and enable a GPIO: the gpio and wdt peripheral modules only. The wdt driver is required to boot and disable the wdt. On reset, the wdt is disabled by the chip, however the QN908x bootloader stored in the internal ROM enables the wdt and sets a timer to reboot after 10 seconds, therefore it is needed to disable the wdt in RIOT OS soon after booting. This patch sets it up such that when no periph_wdt module is used the Watchdog is disabled, but if the periph_wdt is used it must be configured (initialized) within the first 10 seconds. Tests performed: Defined a custom board for this CPU and compiled a simple application that blinks some LEDs. Manually tested with periph_wdt and with periph_wdt_cb as well.
