am335x: make get_board_rev() function weak
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.
In addition open code the trivial and useless BOARD_REV_ID define and
adjust the comment.
