ENGR00176347-5 mx6solo sabreauto: set system_rev
Add set_system_rev function. The layout of system_rev is:
bit 0-7: Chip Revision ID. Read from Anatop register
bit 8-11: Board Revision ID. Read from fuse OCOTP_GP1[15:8]
1: RevA Board
0: RevB board, Unknown board
bit 12-19: Chip Silicon ID. Read from Anatop register
0x63: i.MX 6Dual/Quad
0x61: i.MX 6Solo/DualLite
board_is_rev(system_rev,BOARD_REV_1) can be used to
distinguish RevB board.
board_is_rev(system_rev,BOARD_REV_2) is for RevA board.
