Move boards to boards folder
* boards: rename configs folder to boards
This is the proposed layout after the change:
boards: - folder containing board folders
<board>: - name of each board
drivers: - extra drivers specific for platform
include: - header files for the boars
scripts: - extra scripts specific for platform
src: - board specific code
tools: - extra tools specific for platform
<config>: - board specific configuration(s)
Note:
<xxx> names are dependent on platform
This is a logical change to aim to the arch layout but this is a
huge change it should be done in several steps to lower the risk.
