fsl: common: qixis: Add ifc and emmc switching via qixis

Currently only SD, NAND can be secondary boot sources controlled
by FPGA/CPLD via qixis commands. For SoC like LS1088 IFC-NOR
can be secondary boot source, while QSPI-NOR is the primary.
Add options in qixis to switch to other boot sources including
ifc and emmc.
