Glenn Ruben Bakke 6011441342 nrf: Move pyb module to boards module
Cleaning up use of "pyb" module.
Moving the file to a new folder and updating the
makefile accordingly. New module created called
"board" to take over the functionality of the legacy
"pyb" module.

Updating outdated documentation referring to pyb.Pin,
to now point to machine.Pin.
