From: Nikita Kiryanov <nik...@compulab.co.il>
Current get_board_rev() function returns a hard coded value which is
obviously incorrect for the majority of boards.
Allow boards to provide a correct implementation by making this function
weak.

Changes in v2:
* Changed the way get_board_rev is defined as weak -
remove alias and just add __weak in definition.
