* added: Linker script adds support for RAM4 and RAM5 memory regions, so
that those are usable by code. This also fixes the fact that RAM4 was
declared, but inaccessible previously
* changed: RAM1 is renamed to RAM2, shifting numbering of all regions.
This is done in order to be in line with other STM32 definitions,
similarly ROM1 became ROM2.
* merged: nrf tree from unicore-mx
* fixed: small changes to make merged code play with rest of locm3 again
* added: linker script generator defines for nRF51/52 stubs
* added: doxygen support
This removes code and changes names and styles where relevant to be more
inline with normal libopencm3.
NRF52x library is built for hardfloat, M4F by default. The M4 no float
variants are less common, and if needed, the library can be built
manually for those variants. Unless some very common boards show up
using those parts, we don't need an extra library build.

Updates the main memory map and the makefile.
Adds the SWM050 to devices.data, so that a linker script can be automatically generated.

Fixes some eeprom sizes, and adds all the -a and -x suffix parts.
Note that the explicit endings must be listed _before_ the base parts,
otherwise the matcher will find the wild card first.

The reference manual is incorrect, the data sheet is correct.
There is 320K of ram (up to address 0x20050000). This has been
tested on the STM32F469I-disco board.
The original submitter of this squished everything into one series, and
has not returned. The code mostly appears good, and review comments were
followed for the most part. The project doesn't really maintain any
testing or board farm for sam3/sam4 parts, so we're going to just trust
our users.
