[MIPS] Alchemy: Au1210/Au1250 CPU support
This patch adds IDs for new Au1200 variants: Au1210 and Au1250. They are essentially identical to the Au1200 except for the Au1210 which has a different SoC-ID in the PRId register [bits 31:24]. The Au1250 is a "Au1200 V0.2". Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
