From: Gong Qianyu <qianyu.g...@freescale.com>
QSPI and IFC are pin-multiplexed on LS1043A. So we use
ls1043aqds_sdcard_ifc_defconfig to support IFC in SD boot and
ls1043aqds_sdcard_qspi_defconfig to support QSPI in SD boot. If
QSPI is enabled, IFC should be disabled in kernel as well.

V2:
- Modified rcw file to change core frequency to 1600MHz for SD_BOOT_QSPI.
