ppc4xx: Use CFG_4xx_GPIO_TABLE to configure Sequoia board
Note: this patch changes the configuration of some GPIO registers:
Register Old Value New Value
--------------- ---------- ----------
DCR GPIO0_TCR 0x0000000F 0x0000F0CF
DCR GPIO0_TSRH 0x55005000 0x00000000
DCR GPIO1_TCR 0xC2000000 0xE2000000
DCR GPIO1_TSRL 0x0C000000 0x00200000
DCR GPIO1_ISR2L 0x00050000 0x00110000
