is_erased can take the value 0 (no), 1 (yes), or -1 (unknown).
Checks like (!is_erased) don't do the right thing if it's -1.

If the UICR is already empty, there's no reason to return an error
just because it can't be erased again. This happens, for example,
when flashing UICR from GDB after a "monitor nrf51 mass_erase".

nrf51_erase_page() checks for (sector->offset == NRF51_UICR_BASE) to
determine if the UICR should be erased. However, sector->offset for
the UICR bank is set to 0 in nrf51_probe, so this code is never hit.
Attempting to erase UICR ends up erasing the first flash sector.
Use bank->base instead to determine if UICR is being erased.

The UICR region is actually 0x100 bytes in size. Besides making the
full region accessible, having the right value is important because
GDB rounds flash addresses to the nearest multiple of the block size
when determing which flash blocks to erase.

nRF51 doesn't have any sort of flash page cache so we need to write
all of the data on the word-by-word basis and poll for "Flash Ready"
bit each time.

SoftDevice stack ihex binary, provided by Nordic expects being able to
write data necessary for its correct operation at the adresses inside UICR.
This patch exposes UICR region of flash as a second bank on the MCU to
facilitate that.

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".
