ar71xx: add definitions for RouterBOARD hardware option bits

Browse Source 
Add bit definitions for the 'hardware options' tag which is used in
the MikroTik devices' hardware configurations. These values can be
used in board setup codes, to do different initialization sequences.
The values were obtained from the RouterOS 6.41-rc38 patches.

Additionally, introduce two helper functions what make the processing
of the hardware options easy.
