powerpc/p1010rdb: add p1010rdb-pb support with updating p1010rdb-pa
- Rename old P1010RDB board as P1010RDB-PA. - Add support for new P1010RDB-PB board. - Some optimization. For more details, see board/freescale/p1010rdb/README. Signed-off-by: Shengzhou Liu <Shengzhou.Liu@freescale.com> [York Sun: fix conflicts in boards.cfg] Acked-by: York Sun <yorksun@freescale.com>
