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. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il> Cc: Tom Rini <trini@ti.com>
