feature/hal and photon changes

[m-mcgowan]

Here's a braindump of how the photon differs to the core regarding the surfaces touched by spark-cli:

• USB vendor ID: 0x1D50
• DFU product ID: 0x607F
• USB Serial product ID: 0x607D

In the hal/feature branch the text that is output when the user identifies the device is changed to:
Your device id is 320020001847333531323135

The DFU addresses have changed:

device public key:

• dfu-util -d 2b04:d006 -a 1 -s 1250:294

device private key:

• dfu-util -d 2b04:d006 -a 1 -s 34:612
• cloud public key:
• dfu-util -d 2b04:d006 -a 1 -s 2082:294

server address info:

• dfu-util -d 2b04:d006 -a 1 -s 2466:128
  (It's still possible to write the combined server public key and server address info, as was done for the core.)

The text when identifying the device ID over serial has changed slightly:
Your device id is 2c001b001947333531323135

..aaand that's it. at least what I can think of so far. I'll add comments below if there's more. 🔦
