armv8: ls1088aqds: Add IFC-NOR as boot source for LS1088

IFC-NOR and QSPI-NOR pins are multiplexed on SoC, so they cannot be
accessed simultaneously. IFC-NOR can be accessed along with SD-BOOT.

Ls1088aqds_sdcard_ifc_defconfig is default config for SD boot and
IFC-NOR to be used as flash. This allows writing to IFC-NOR flash.
QSPI and DSPI cannot be accessed in this defconfig.
IFC-NOR image is generated using ls1088aqds_defconfig.
