[U-Boot] [PATCH v2 4/6] omap3: make get_board_rev() function weak

[Igor Grinberg]

From: Nikita Kiryanov <nikita at 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.
