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

Browse Source 
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.
