PATCH 1/1 ls102xa: fdt: Disable QSPI and DSPI in NOR/NAND/SD boot

As QSPI/DSPI and IFC are pin multiplexed, QSPI and DSPI are only enabled in QSPI boot, and disabled in other boot modes. IFC is enabled in NOR/NAND/SD boot, and disabled in QSPI boot. This patch will add fdt support for the above rules.
