When booting a Freescale kernel 3.0.35 on a Wandboard solo, the get_board_rev() returns 0x62xxx, which is not a value understood by the VPU (Video Processing Unit) library in the kernel and causes the video playback to fail.

The expected values for get_board_rev are: 0x63xxx: For mx6quad/dual 0x61xxx: For mx6dual-lite/solo

So adjust get_board_rev() accordingly and make it as weak function, so that we do not need to define it in every mx6 board file.
