nrf51: Add a known devices table and simple chip type detection code

Unfortunately due to my oversight, the original version of the
nrf51_probe function contained useless code that read the contents of
DEVICEID[0] an DEVICEID[1] registers and did nothing about it(those
registers had nothing to do with the device type information anyway).

This commit fixes that code by changing its behavior to read the HWID
field of CONFIGID register and looking up the corresponding device
information in the know devices table. This information is useful
when choosing the versions of SDK and SoftDevice for the chip
using "nRF51822 compatibility matrix".
