Implements MCU-specific GPIO input interrupt integration. Added
definition of System configuration controller as well as its needed by
the GPIO code.
The SYSCFG controller is used for system-specific configuration such as:
- remap the type of memory accessible at address 0x00000000
- manage the external interrupt line connection to GPIOs
- configure the I/O compensation cell

The baudrate calculation present in set_baudrate() is
causing the UART to emit inital bytes incorrectly, for a
reason currently unknown, but directly related to the fact
that __aeabi_uldivmod is being invoked.
Since the nRF5x Product Specifications do not provide a
standard formula to calculate baudrates and instead list
a predefined set of divisor values, we opt here to use the
official values and remove the attempt at calculating them
manually.

There was a reference to SOC_FAMILY_NRF5 which was not use by anyone
else and it seemes like it was a typo, where the right reference was
to symbol SOC_NRF5. However, the right fix is to move both sites to
use SOC_FAMILY_NRF5 *and* fix the SOC_SERIES to be only nrf52,
otherwise it causes path duplication and the build fails.
This was also causing documentation warnings that are thus killed.
